摘　　要：以汉麻废弃物为原料,通过KMnO4氧化处理,制备了表面富含Mn-O基团的改性汉麻吸附材料,研究了改性汉麻吸附材料对水体中重金属离子吸附性能。改性汉麻吸附材料对水体中Pb2+吸附容量比改性前提高4倍多。改性汉麻吸附材料吸附容量达37.86mg·g^(-1)。KMnO4改性汉麻材料具有易制备、价廉环保等优点。Using Hemp waste as raw material,the modified Hemp adsorption material with rich Mn-O groups on the surface was prepared by KMnO4 oxidation treatment.The adsorption properties of the modified Hemp adsorbent for heavy metal ions in water were studied.The adsorption capacity of modified Hemp adsorbent for Pb2+in water is more than 4 times higher than that before modification.The adsorption capacity of modified Hemp adsorbent was 37.86mg·g^(-1).KMnO4 modified Hemp adsorbent has the advantages of easy preparation,low price and environmental protection.
