Abstract
Increasing apprehension about water pollution has stimulated the pursuit of sustainable remedies, resulting in an upsurge in scholastic investigations that focus on biobased material for wastewater treatment. Since ages adsorption through activated carbon (AC) has been considered a reliable method. This study has examined different surface chemistry techniques utilized in biobased ACs for pollutant absorption from wastewater. Successful creation of eco-friendly adsorbents, from natural biomaterials like plant-derived fibers, biopolymers, and biofunctionalized surfaces, has efficiently eliminated metallic contaminants from wastewater. ACs derived from plant wastes are a favorable choice due to cost-effectiveness, biodegradability, minimal sludge generation, high regression percentage, and efficient metal adsorption capabilities. In addition, this study highlights their ability to be scaled up, their affordability, and their positive impact on the environment. The field of surface chemistry of biobased materials is constantly evolving through interdisciplinary collaborations between chemists, materials scientists, and environmental engineers. This progress offers promising avenues for addressing the urgent challenges of water pollution and contributing to the development of a cleaner and healthier environment. This review compiles the latest literature on AC production from various biowaste sources, utilizing different methods such as physical, chemical, or thermochemical activation, ultrasonication, and oxidation. The focus is on its application in waste water treatment, specifically in metal adsorption.
人们对水污染的忧虑与日俱增，这刺激了人们对可持续补救措施的追求，导致学术界对用于废水处理的生物基材料的研究激增。自古以来，通过活性炭（AC）进行吸附一直被认为是一种可靠的方法。本研究考察了生物基活性炭用于吸附废水中污染物的不同表面化学技术。利用天然生物材料（如植物纤维、生物聚合物和生物功能化表面）成功制造出的生态友好型吸附剂可有效去除废水中的金属污染物。从植物废弃物中提取的 AC 具有成本效益高、可生物降解、产生的污泥量少、回归率高以及高效的金属吸附能力等优点，因此是一种不错的选择。此外，本研究还强调了它们的放大能力、经济性以及对环境的积极影响。通过化学家、材料科学家和环境工程师之间的跨学科合作，生物基材料的表面化学领域正在不断发展。这一进展为应对水污染的紧迫挑战和促进更清洁、更健康环境的发展提供了前景广阔的途径。本综述汇编了利用不同方法（如物理、化学或热化学活化、超声波处理和氧化）从各种生物废料中生产 AC 的最新文献。重点是其在废水处理中的应用，特别是在金属吸附方面的应用。
