Among biopolymer-based adsorbents, composites in the form of beads have shown promising results in terms of high adsorption capacity and ease of separation from the effluents. This review addresses the potential of biopolymer-based beads to remediate wastewaters polluted with emerging organic contaminants, for instance dyes, active pharmaceutical ingredients, pesticides, phenols, oils, polyaromatic hydrocarbons, and polychlorinated biphenyls. High adsorption capacities up to 2541.76 mg g for dyes, 392 mg g for pesticides and phenols, 1890.3 mg g for pharmaceuticals, and 537 g g for oils and organic solvents have been reported. The review also attempted to convey to its readers the significance of wastewater treatment through adsorption by providing an overview on decontamination technologies of organic water contaminants. Various preparation methods of biopolymer-based gel beads and adsorption mechanisms involved in the process of decontamination have been summarized and analyzed. Therefore, we believe there is an urge to discuss the current state of the application of biopolymer-based gel beads for the adsorption of organic pollutants from wastewater and future perspectives in this regard since it is imperative to treat wastewater before releasing into freshwater bodies.
在基于生物聚合物的吸附剂中，珠粒形式的复合材料在高吸附容量和易于从废水中分离方面显示出了有前景的结果。本综述探讨了基于生物聚合物的珠粒在修复受新兴有机污染物（例如染料、活性药物成分、农药、酚类、油类、多环芳烃和多氯联苯）污染的废水中的潜力。已经报道了高达 2541.76 mg g 对染料的高吸附容量、392 mg g 对农药和酚类的高吸附容量、1890.3 mg g 对药物的高吸附容量以及 537 g g 对油类和有机溶剂的高吸附容量。该综述还试图通过提供关于有机水污染物的去污技术概述，向读者传达通过吸附进行废水处理的重要性。总结和分析了基于生物聚合物的凝胶珠的各种制备方法和去污过程中涉及的吸附机制。因此，我们认为有必要讨论当前基于生物聚合物的凝胶珠用于从废水中吸附有机污染物的应用现状和未来展望，因为在将废水排入淡水体之前对其进行处理至关重要。
