Today, with the growth of the human population, industrial activities have also increased. Different industries such as painting, cosmetics, leather, etc. have broadly developed, and as a result, they also produce a lot of pollutants. These pollutants can enter the environment and pollute water, air, and soil. Organic dyes, nitro compounds, drug residues, pesticides and herbicides are pollutants that should be removed from the environment. Natural polymers or biopolymers are important types of organic materials that are broadly applied for different applications. Among them, polysaccharides and lignin, which are two types of biopolymers, have attracted much consideration owing to their advantages such as biocompatibility, environmental friendly, safety, availability, etc. Polysaccharides include cellulose, gum, starch, alginate (Alg), chitin, and chitosan (CS). On the other hand, bentonite is one of the types of clays, which owing to their properties like large specific surface area, adsorption performance, naturally available, etc., have drawn the interest of many researchers. As a result, the synthesis of a composite including polysaccharide/lignin and bentonite can be very efficient for different applications, especially environmental ones. In this review, we instigated the preparation of these composites as well as the removal performance of them. In fact, we reported recent advancements in the synthesis of lignin- and polysaccharide-bentonite composites for the removal of diverse kinds of contaminants like organic dyes, nitro compounds, and hazardous materials.
如今，随着人口的增长，工业活动也有所增加。不同的行业，如绘画、化妆品、皮革等，都有了广泛的发展，因此也产生了大量的污染物。这些污染物可以进入环境，污染水、空气和土壤。有机染料、硝基化合物、药物残留、农药和除草剂是需要从环境中去除的污染物。天然聚合物或生物聚合物是重要的有机材料类型，广泛应用于不同的应用领域。其中，多糖和木质素作为两种生物聚合物，由于其具有生物相容性、环境友好性、安全性、可用性等优点，引起了人们的广泛关注。多糖包括纤维素、树胶、淀粉、藻酸盐（Alg）、甲壳素和壳聚糖（CS）。另一方面，膨润土是粘土的一种类型，由于其具有大的比表面积、吸附性能、天然可用性等特性，引起了许多研究人员的兴趣。因此，合成包括多糖/木质素和膨润土的复合材料对于不同的应用，特别是环境应用，可能非常有效。在这篇综述中，我们探讨了这些复合材料的制备以及它们的去除性能。实际上，我们报道了最近在合成木质素和多糖膨润土复合材料方面的进展，用于去除各种污染物，如有机染料、硝基化合物和有害物质。
