ABSTRACT Freeze desalination (FD) is an efficient technology to produce fresh water through formation of ice crystals in the seawater or brackish water and subsequent separation of salt (or other components) from the pure ice fraction. FD development has been focused primarily on two areas, the purification of ice portion, and a significant increase in desalination productivity, allowing a considerable decrease in energy consumption. However, only laboratory and pilot-scale FD studies have been conducted, and actually, the possible industrial FD applications have been limited due to the predominance of thermal- and membrane-based desalination technologies. Whereby, the focus of this review is on the general principles, advantages and disadvantages of FD, and in addition, this article discusses the environmental impact of FD and other desalination systems in brine-loaded media discharged into aquatic environment.

ABSTRACT Increasing applications of precious metals (PMs: Au, Ag and platinum group metals) and the growing demand is a matter of great concern for supply security. The hydrometallurgical route through chloride-based leaching has been considered as the most promising method to recover almost all the metals. However, separation of metal-chloro complexes formed during the leaching is difficult to achieve because of similar properties of these complexes. Among the methods developed to extract and separate the metal-chloro complexes, ionic liquid (IL)-based solvent extraction has been recognized as one of the most promising approaches. The ionic liquids possess unique characteristics of ‘greener,’ ‘designer’ and ‘highly effective’ solvents. This paper reviews extraction and separation of PM-chloro complexes by ionic liquids. Mechanisms and IL role in the process, along with merits and drawbacks of IL-assisted solvent extraction are discussed comprehensively. Effects of operational conditions, stripping, and regeneration of the loaded ILs and possible use of ionic liquids in other separation methods are also presented. A flow-sheet for separation of PM-chloro complexes has been developed as a part of basic process approach using ionic liquids. In addition, future directions for the development and application of IL-assisted solvent extraction in separation of precious metals are provided.

ABSTRACT Silicon carbide (SiC) nanomaterials are being used in a large range of fields because of their excellent mechanical strength, high thermal resistance and conductivity, high chemical stability and being semiconductors. In the present review, we evaluate SiC nanomaterials as membranes and adsorbents to separate different species. In addition, applications of SiC nanomaterials as membranes or in a membrane structure are described. In this regard, experimental studies which used porous SiC in membrane structure confirmed that SiC can enhance the performance of any membrane because of its large surface area, anti-fouling nature, high porosity, and high-water permeability. Next, molecular dynamics simulation studies examined the ability of SiC nanosheets and SiCNTs in water desalination, gas and dissolved molecule separations. Ultimately, based on the reviewed articles and their findings, areas requiring further attention by researchers are proposed.

ABSTRACT Ionic liquid (IL)-based surfactants exhibit prominent properties in adsorption and aggregation, providing strong influence on interfacial properties of phases. This review overviews the main characteristics of IL-based surfactants and their versatility in different processes particularly those dealing with the stabilization of immiscible liquids and solids for the aim of producing microemulsions and micelles. Applications in separation processes for chromatographic and extraction techniques and in the petroleum industry for augmenting the oil recovery, separation of asphaltene and paraffin deposits and crude oil separation are precisely studied by describing the mechanisms as well as qualitative and quantitative comparison to conventional surfactants everywhere relevant. These are particularly highlighted with respect to the importance of selecting/tailoring the desired IL-based surfactants in relation to the influence of operating parameters. Moreover, challenges and directions of the future outlooks on specific topics are discussed.

ABSTRACT One of the requirements for the treatment of drinking water is the removal of pathogenic microorganisms. Typically, the most used techniques apply inorganic nanoparticles or chlorine release precursors to inactivate bacteria. While these treatments are very effective, they tend to show a decrease in antimicrobial activity over time, releasing potentially toxic ions and contributing to bacterial resistance. In this sense, the development of hydrogel-based materials has become a potential alternative for water disinfection. The synthesis and functionalization of hydrogels have been proven to improve the global performance of microorganism retention. Our work provides an overview of the synthesis and functionalization of hydrogel-based materials, their advantages and limitations, and the latest research on the use of hydrogels for water disinfection. The future panorama of hydrogel-based materials applicability for water treatment is also provided. The main challenge to expand the use of hydrogels in water treatment is the lack of research assessing the feasibility of large-scale applicability of these materials, considering real systems. Most of the studies carried out experiments at laboratory scale with controlled situations, in which interactions between microorganisms and real world contaminants were not considered.

ABSTRACT Surface ion-imprinting technology (SIIT) is a novel and effective alternative to conventional methods of preparing ion-imprinted polymers. SIIT involves the coating of support materials with a polymeric layer that selectively binds with imprinted metal ions, particularly heavy metal ions. Given its specificity, predictability, and stability, SIIT has been quickly adopted in ion detection, separation, enrichment, and sensing. Here, building on the latest advances in this emerging new technology, we carried out a systematic review to summarize the 1) principles and basic components of surface ion-imprinted polymers (SIIPs); 2) preparations, properties, advantages, and disadvantages of three types of SIIP supporting materials, including inorganic (minerals, carbonaceous materials, metal oxides), organic, and composite (organic/organic, organic/inorganic, inorganic/inorganic) supports; 3) current applications of SIIT, and 4) future challenges and opportunities related to SIIT. Finally, perspectives and future research are discussed to address the pressing need for the development of SIIT for heavy metal ion treatment.

ABSTRACT In groundwater, excess fluoride concentration (>1.5 mg/L) is a primary concern for various countries. Nanoadsorbents have been proven to possess higher adsorption capacity than conventional adsorbents. This review aims to provide insights into recent advancements in the adsorption of fluoride using various nanoadsorbents. Nanoparticles have very high specific surface area but are usually found unsuitable for real field applications as they tend to agglomerate. They are also difficult to recover after use and pose a significant threat to the environment through leaching. These limitations have given rise to the trend of the development of nanocomposites for defluoridation. Nanocomposites often involve a polymeric matrix that serves as a medium for their homogenous dispersion. This reduces agglomeration and leaching into the surroundings without altering the original activities of the nanoadsorbent. This review classifies the fluoride nanoadsorbents into three categories: bare nanoparticles, nanocomposites with nanoparticles inside the porous matrix, and nanocomposites with nanoparticles coated with or anchored on the matrix surface. Critical analyses of the importance and shortcomings of these classes have been presented. In general, bare nanocomposites show the best fluoride adsorption performance compared to other classes of nanoadsorbents.

ABSTRACT The combination of membranes and microfluidic systems has been applied in areas such as bioscience, environmental and analytical chemistry, and in the past time research into the integration of membrane mass transfer control functions into microfluidic devices has shown a significant growth trend. The multiple uses of membrane-based microfluidic systems have been demonstrated in published reports. The aim of this paper is to provide an overview of the development process in this field, starting with the basic terminology of microfluidic and membrane processes and outlining membrane-based microfluidic platforms that combine the two, followed by a classification of membrane integration on a chip based on the preparation methods used to combine the two. Three membrane functions that membranes can perform in microfluidic systems are then discussed; they are separation and enrichment of substances, immobilization and culturing of cells, and fluid control of pumps and valves. Finally, several possible research directions and related issues for membrane-based microfluidic platforms are presented, providing a deeper reference for future research combining membranes with microfluidic platforms.
