聚丙烯酰胺类复合材料吸附废水中Pb2+的研究进展

摘要

Polyacrylamide(PAM) and its composites play an important role in the treatment of heavy metal ions ,be-cause it contains various kinds of functional groups and its high adsorpability for heavy metal ions.The research pro-gress in the application of PAM composite materials to the adsorption of heavy metal Pb2+ from wastewater in recent years is summarized.The influences of the factors,such as Pb2+ initial concentration,adsorbent dosage,temperature, adsorbent particle size,adsorption time,pH of solution,coexisting ions,etc.on PAM composite materials for the ad-sorption of Pb2+,and its adsorption mechanisms are expounded.At the end,combined with its research situation and existed problems,some suggestions and prospect about its future research are put forward.%聚丙烯酰胺(PAM)及其复合物由于含有多种功能基团和良好的金属离子吸附性能,在重金属处理领域起到重要作用.综述了近年来PAM复合材料吸附废水中重金属Pb2+的应用研究进展;阐述了Pb2+初始浓度、吸附剂投加量、温度、吸附剂粒径、吸附时间、溶液pH及共存离子等因素对PAM类复合材料吸附Pb2+的影响及吸附机理;最后,结合其研究现状和存在的问题对未来的研究进行了建议和展望.
