Photo/sono-catalytic techniques are being extensively considered for the degradation and removal of emerging contaminants (EC), including pharma-based organic pollutants. Transition metal-based nanomaterials have been studied as adsorbent/catalytic material in photo/sono-catalytic techniques for complete elimination/degradation/mineralization of pharmaceutical-based EC from wastewater streams. Various structural properties with dimensionalities of earth-abundant base metals (Ni, Fe, Cu, and Zn) oxides and their doped hybrid/composites, have been recently studied for removal/degradation/mineralization of EC from solution on the laboratory scale and industrial effluent of pharma-sectors. The oxides of earth-abundant base metals nanomaterials have been summarised and discussed in this review along with the general mechanism of degradation/elimination with acceptable results related to wastewater stream detoxification and recyclability of catalytic material during degradation/removal of EC. The surface properties like transfer of electrons and holes, surface area, surface modification and doping with reusability value of these materials are primacy factors for their applicability in the degradation/removal of organic pollutants from wastewater and substantial treatment. This study would be helpful for their use and development of cutting-edge materials for waste/surface water treatment on a large scale in a sustainable and cost-effective manner.

The Anaerobic Digestion Model No. 1 (ADM1) is a widely spread platform for simulating methanogenic reactors. It is a structured and complex model considering physicochemical and biochemical processes during wastewater and sewage sludge anaerobic digestion (AD). However, many modifications, simplifications, and adaptions exist for specific wastewaters/sludges, processes, and operational conditions. Given this, a bibliometric analysis was carried out to identify the main applications of ADM1 in the dry anaerobic digestion (D-AD) of fruit and vegetable waste (FVW), food waste (FW), and organic fraction of municipal solid waste (OFMSW). The adaptation necessary in ADM1 includes adjusting and separating the disintegration and hydrolysis rates of the substrate and sludge, which have different characteristics, such as the concentration of solids, which is inversely proportional to the hydrolysis velocity. In addition, adaptations are a function of the adopted reactor and other parameters. Finally, the work identifies the current modeling state-of-the-art using ADM1 and the need for further research to improve the model application in D-AD processes.

Each nation has chosen a double-carbon (carbon neutrality/emission peak) policy in line with the objectives of the Paris Agreement to meet human development demands. An estimated 8 million tons of plastic waste related to the epidemic have been generated globally, highlighting an urgent need to halt or at least reduce plastic pollution. The research on degradable polymers that can decompose during composting or under illumination is becoming increasingly crucial. This paper provides a summary of various ester-bonded degradable plastic polymers, including concepts and mechanisms related to water degradation, photo degradation, and bio degradation. It also reviews important degradable agents and examines several ester-bonded plastic polymers currently used in commerce. The limitations and potential applications of these ester-bonded degradable polymers are compared and discussed. It is believed that understanding degradation will contribute to driving the development of degradable packaging polyesters.

Insects are a promising group of animals for value-added biorefining products. Among other insects, the Black Soldier Fly (BSF) Hermetia illucens has gained more attention for extracting chitin and chitosan. Chitin is a natural polysaccharide well-known for its structural integrity and biocompatibility. The outer shell or exoskeletons of insects are made up of chitin, a linear polymer of N-acetylglucosamine that provides mechanical support. The BSF H. illucens serve as a best alternative source for extracting natural biopolymer chitin and chitosan. Despite their potential, no comprehensive review of BSF-derived chitin and chitosan has been published. This review aims to provide an extensive overview of recent updates on the possible applicability of BSF chitin and chitosan for biomedical and industrial applications. Special attention is given to the BSF’s biology, extraction procedures, physicochemical characterization and their biomedical applications such as antioxidant, antibacterial, wound healing properties and their various industrial claims. Furthermore, limitations, challenges, and future recommendations on extracting chitin and chitosan from BSF were also discussed. Overall, this review highlights the potential role of BSF derived chitin and chitosan in various industrial platforms.

Ceramic membranes (CMs) demonstrated significant potential in removing sulfamethoxazole (SMX) from wastewater due to their superior properties to conventional polymeric membranes, including chemical and thermal stability, fouling resistance, and extended operational lifespan. However, conventional CMs were ineffective in removing SMX from wastewater, which led to the development of advanced CMs, utilizing catalysts and hybrid membranes to enhance wastewater treatment performance, particularly for SMX removal. This review critically examined the advancements in catalytic CMs, focusing on those activated by peroxymonosulfate, which showed remarkable efficacy in industrial and hospital wastewater treatment. It also explored the development of novel ceramic materials, advanced activation techniques, and integration of CMs with other treatment technologies. Significant benefits, such as robust mechanical properties and self-cleaning capabilities, rendered these membranes ideal for complex wastewater treatment scenarios. Furthermore, the ceramic membrane market was growing rapidly, with declining costs and long-term economic efficiency; however, challenges remained in ensuring economic feasibility and addressing potential nano- and micro-pollutant emissions. Optimizing catalytic activity, enhancing material durability, reducing operational costs, and conducting comprehensive studies on long-term performance, scalability, and environmental impacts were necessary. Moreover, these membranes' practical applicability and effectiveness needed validation through extensive case studies and large-scale pilot projects to improve the sustainability and efficiency of wastewater treatment solutions, addressing existing challenges while fostering continuous innovation in the field.
陶瓷膜(CMs)在去除废水中的磺胺甲噁唑(SMX)方面表现出巨大潜力,这是因为陶瓷膜具有优于传统聚合物膜的特性,包括化学和热稳定性、抗污损性和更长的运行寿命。然而,传统的聚合膜在去除废水中的 SMX 方面效果不佳,这促使人们开发先进的聚合膜,利用催化剂和混合膜来提高废水处理性能,尤其是去除 SMX 的性能。本综述批判性地研究了催化 CM 的进展,重点关注那些在工业和医院废水处理中表现出显著功效的过硫酸盐活化 CM。报告还探讨了新型陶瓷材料的开发、先进的活化技术以及 CM 与其他处理技术的整合。这些膜具有强大的机械性能和自清洁能力等显著优势,是复杂废水处理方案的理想选择。此外,陶瓷膜市场增长迅速,成本不断下降,具有长期经济效益;但在确保经济可行性和解决潜在的纳米和微污染物排放方面仍存在挑战。必须优化催化活性、提高材料耐久性、降低运营成本,并对长期性能、可扩展性和环境影响进行全面研究。此外,还需要通过广泛的案例研究和大规模试点项目来验证这些膜的实际适用性和有效性,以提高废水处理解决方案的可持续性和效率,在解决现有挑战的同时促进该领域的持续创新。

Environmental pollution has become a pressing issue in today's world. With the acceleration of industrialization and urbanization, a large number of harmful gases and solid wastes are discharged into the atmosphere, water and soil, resulting in a sharp decline in environmental quality. Nanofibrous materials have attracted much attention due to their excellent physicochemical properties, controllable release and environmental friendliness. As a new type of nanomaterial, nanofibrous membranes (NFMs) has shown great potential in environmental treatment. Among numerous methods for the preparation of NFMs, electrospinning is a green technology. The NFMs obtained by this technique have the advantages of adjustable morphology, high specific surface area and controllable pore structure, which can provide more active centers for the adsorption of pollutants from water and the atmosphere. Based on a brief introduction of the principle of electrospinning, this paper focuses on the application of electrospun NFMs in environmental remediation, including the adsorption of organic dyes, adsorption of heavy metal ions, adsorption of antibiotics and other drugs, elimination of bacteria, air purification and so on.

Gas hydrates phase transition is crucial for energy exploitation, natural gas transportation and CO2 capture storage fields. This review introduces the characteristics of gas hydrate in phase transition process including the thermodynamic and kinetic characters, the dissociation and reformation characters, and the promotion methods. The phase equilibrium conditions of gas hydrate determine its thermal properties, but some accurate statistical studies are needed to obtain a variety of phase equilibrium experimental results in the future. In addition, it is necessary to quantify the factors of hydrate nucleation and provide an accurate induction time prediction model due to the randomness of the nucleation process. In hydrate exploitation applications, the depressurization and heat injection methods may be hindered due to the limitation of temperature, pressure, inhibitor and heat transfer characteristic. It will cause the hydrate reformation phenomenon and further influence the hydrate exploitation efficiency. Controlling the hydrate exploitation process requires a more systematic combination of decomposition methods, and further proving the influence factors such as memory effect and nanobubbles for the hydrate reformation. Besides, the promotion for gas hydrate phase transition also has been studied to make the hydrate rapid formation in the industrial fields come true. Stirring, spraying, bubbling method and additives are available for the promotion. However, the energy cost and efficiency improvement of hydrate formation promotion process need to be further studied. At last, several gas hydrate applications are proposed, including CO2 capture and sequestration, natural gas storage, seawater desalination, cold storage, mixed gas separation and sewage treatment. This review presents an overall analysis of gas hydrate phase transition from characteristics to applications and contributes a reference for future development in hydrate technology.

Low-carbon alcohol azeotropic systems are widely present in various industrial fields such as chemicals, pharmaceuticals, and food, creating an urgent need for the development of efficient and cost-effective separation technologies to meet the growing market demand. Extraction, as an economical and effective method for separating azeotropic mixtures, relies heavily on the choice of extracting agents. Due to the unique physical properties of ionic liquid (ILs) and the importance of the extraction process, an increasing number of researchers are utilizing ILs as extracting agents. This paper reviews recent advances in the two-phase behavior studies of ILs for separating low-carbon alcohol systems, detailing the application of molecular simulation in phase equilibrium research. Additionally, it describes the liquid-liquid extraction separation model of ILs for low-carbon alcohols, revealing that the NRTL model performs well during the fitting process. Finally, the paper explores the mechanism analysis, experimental studies, and simulation research progress of using ILs as extracting agents for the separation of low-carbon alcohol systems.

This paper reviews recent advances in the two-phase behavior studies of ILs for separating low-carbon alcohol systems, detailing the application of molecular simulation in phase equilibrium research. Additionally, it describes the liquid-liquid extraction separation model of ILs for low-carbon alcohols, revealing that the NRTL model performs well during the fitting process. Finally, the paper explores the mechanism analysis, experimental studies, and simulation research progress of using ILs as extracting agents for the separation of low-carbon alcohol systems.</div></div>","PeriodicalId":15759,"journal":{"name":"Journal of Environmental Chemical Engineering","volume":"12 6","pages":"Article 114609"},"PeriodicalIF":7.4,"publicationDate":"2024-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142561521","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since the discovery of MXenes in 2011, considerable research has been conducted on the diverse applications of MXenes, encompassing areas such as electrochemical sensing. It is crucial to develop electrochemical sensors with high selectivity and sensitivity. Several nanostructured materials have been contemplated for the fabrication of electrochemical(bio)sensors, aiming to attain superior selectivity and sensitivity. Lately, MXenes have attracted considerable interest as electro-active modifiers in developing electrochemical sensors, owing to their distinctive chemical and physical characteristics as 2D nanomaterials. MXenes possess attributes such as high conductivity, hydrophobicity, and expansive specific surface areas, capturing the interest of researchers across various fields. This includes environmental water engineering applications such as desalination and wastewater treatment and the design and construction of efficient sensors for detecting hazardous environmental pollutants. This study provides a concise overview of the utilization of electrochemical sensors based on MXenes for detecting environmental toxic pollutants, including pharmaceuticals, heavy metals, pesticides, and more. The paper delves into the synthetic methods and characteristics of MXenes. Furthermore, it explores the integration of molecular imprinted polymers (MIPs), metal nanoparticles, and other carbon nanostructured materials to enhance the sensitivity and selectivity of MXene-based sensors. Moreover, it addresses the main challenges and provides perspectives on future research directions.
