Toxic wastes like heavy metals and dyes are released into the environment as a direct result of industrialization and technological progress. The biosorption of contaminants utilizes a variety of biomaterials. Biosorbents can adsorb toxic pollutants on their surface through various mechanisms like complexation, precipitation, etc. The quantity of sorption sites that are accessible on the surface of the biosorbent affects its effectiveness. Biosorption's low cost, high efficiency, lack of nutrient requirements, and ability to regenerate the biosorbent are its main advantages over other treatment methods. Optimization of environmental conditions like temperature, pH, nutrient availability, and other factors is a prerequisite to achieving optimal biosorbent performance. Recent strategies include nanomaterials, genetic engineering, and biofilm-based remediation for various types of pollutants. The removal of hazardous dyes and heavy metals from wastewater using biosorbents is a strategy that is both efficient and sustainable. This review provides a perspective on the existing literature and brings it up-to-date by including the latest research and findings in the field.
诸如重金属和染料之类的有毒废物作为工业化和技术进步的直接结果被排放到环境中。污染物的生物吸附利用了多种生物材料。生物吸附剂可以通过络合、沉淀等各种机制在其表面吸附有毒污染物。生物吸附剂表面可利用的吸附位点数量会影响其有效性。与其他处理方法相比,生物吸附的低成本、高效率、无需营养以及生物吸附剂可再生的能力是其主要优势。优化温度、pH值、养分可用性等环境条件以及其他因素是实现生物吸附剂最佳性能的先决条件。近期的策略包括针对各类污染物的纳米材料、基因工程和基于生物膜的修复。使用生物吸附剂从废水中去除有害染料和重金属是一种高效且可持续的策略。本综述提供了对现有文献的观点,并通过纳入该领域的最新研究和发现使其与时俱进。
