摘　　要：近年来,水中污染物对人类健康的影响引起了人们广泛关注,以农林废弃物等为原料制备的生物炭是一种高效低成本吸附剂,已被用于去除水中污染物。为进一步提高生物炭的吸附性能,有必要对生物炭进行功能化改性。关于改性生物炭吸附去除水中污染物的报道较多,这些研究探索了各种生物炭功能化改性方法,表明不同改性生物炭对不同污染物具有不同的吸附行为和机制。综述了近5年来改性生物炭吸附去除水中污染物的方法,并对改性生物炭吸附剂在未来废水处理中的发展方向进行展望。In recent years,the impact of pollutants in water on human health has attracted wide attention.Biochar prepared from agroforestry wastes is an efficient and low-cost adsorbent,which has been used to remove pollutants from water.In order to further improve the adsorption performance of biochar,it is necessary to functionalize and modify biochar.There are many reports on the adsorptive removal of pollutants from water by modified biochar.These studies explore various biochar functionalization modification methods and demonstrate that different modified biochar have different adsorption behaviors and mechanisms for different pollutants.This paper reviewed the methods of modified biochar for removing pollutants from water in the last five years and provided an outlook on the future direction of modified biochar adsorbents in wastewater treatment.
