今天,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。已经广泛发展,结果,它们还产生大量的污染物。这些污染物会进入环境,污染水源,空气,和土壤。有机染料,硝基化合物,药物残留,杀虫剂和除草剂是应该从环境中去除的污染物。天然聚合物或生物聚合物是广泛用于不同应用的重要类型的有机材料。其中,多糖和木质素,这是两种类型的生物聚合物,由于它们的生物相容性等优点,吸引了很多考虑,环境友好,安全,可用性,等。多糖包括纤维素,口香糖,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,由于它们的特性,如大的比表面积,吸附性能,自然可用,等。,引起了许多研究人员的兴趣。因此,包括多糖/木质素和膨润土的复合材料的合成对于不同的应用是非常有效的,尤其是环保的。在这次审查中,我们促进了这些复合材料的制备以及它们的去除性能。事实上,我们报道了木质素和多糖膨润土复合材料的合成的最新进展,用于去除各种污染物,如有机染料,硝基化合物,和危险材料。
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.
