聚丙烯酰胺类复合絮凝剂对金属离子吸附的研究进展

Review on composite flocculant of polyacrylamide and its derivative adsorption of metal ions

介绍了近年来聚丙烯酰胺(PAM)与无机有机化合物、纳米材料等的复合絮凝剂种类及各自的吸附特点,并阐述了改性后的絮凝剂对重金属离子Pb^(2+)、Cr^(6+)/Cr^(3+)、Ni ^(2+)、Cu^(2+)、Cd^(2+)、Hg^(2+)等的吸附效果,及对轻金属Zn^(2+)、Ca^(2+)、Li^+、Fe^(3+)的研究现状,通过改性的絮凝剂比原本单一的絮凝剂对金属离子的去除效果更好且更经济实惠。

The types and their adsorption characteristics of inorganic organic compounds,natural polymer compound,nano materials which combined with PAM in recent years were introduced.And also expounded the removal effciency of heavy metal Pb2＋,Cr6＋/Cr3＋,Ni 2＋,Cu2＋,Cd2＋and Hg2＋,the research status of light metal Zn2＋,Ca2＋,Li＋ andFe3＋,Which were on treated modified flocculant.The removal ions efficiency and the price of modified flocculant were better than the original single flocculant.
