摘要: 研究了以水杨醛改性的壳聚聚糖及其衍生物对Ph2+,Zn2+,Co2+的静态吸附性能结果表明,该类吸附剂对巩Pb2+,Zn2+具有良好的吸附性能,其吸附量可分别达455.2和105.5mg·g-1,并能在Co2+存在下选择吸附Ph2+和Zn2+.Abstract: The static adsorption properties for metal ions (Pb2+, Zn2+, Co2+) of chitosan modified by salicylaldehyde and its derivatives have been studied.The results show that the adsorbents have good adsorption characterization and good adsorption selectivity for Pb2+ and Zn2+ when Co2+ is coexistence.The adsorption capacities for Pb2+455.2, 105.5mg·g-1 resin respectively.
