In recent years, various industrial activities have caused serious pollution to the environment. Due to the low operating costs and high flexibility, adsorption is considered as one of the most effective technologies for pollutant management. Agricultural waste has loose and porous structures, and contains functional groups such as the carboxyl group and hydroxyl group, so it can be invoked as biological adsorption material. Agricultural waste gets the advantages of a wide range of sources, low cost, and renewable. It has a good prospect for the comprehensive utilization of resources when used for environmental pollution control. This article summarized the current research status of agricultural waste in adsorbing pollutants, which pointed out the influencing factors of adsorption, expounded the adsorption mechanism of biological adsorption and introduced the related parameters of adsorption, proposed the application of adsorbents in engineering including adsorption in liquid and gas phases, at the same time it gave the future development prospect of agricultural waste as adsorbent.

近年来，各种工业活动已对环境造成严重污染。由于较低的运行成本和较高的灵活性，吸附被认为是最有效的污染物管理技术之一。农业废料具有疏松多孔的结构，并含有羧基和羟基等官能团，因此可以用作生物吸附材料。农业废料具有来源广泛，成本低廉和可再生的优点。将其用于环境污染控制，具有资源综合利用的良好前景。本文总结了农业废弃物吸附污染物的研究现状，指出了影响吸附的因素，
