摘要:
淀粉经环氧氯丙烷交联后, 以FeSO4 -H2O2 或(NH4)2Ce (NO3)6 为引发剂, 将丙烯腈接枝到高交联淀粉上, 接枝产物 再经皂化水解制得水不溶性羧基淀粉接枝聚合物(简称羧基淀粉)。研究了在不同的交联和接枝条件下, 产品对Cr3 +、Cd2 +重 金属离子的吸附性能, 为其应用提供了依据。
Abstract:
Water -insoluble carbo xyl -containing starch graf t polymer (carboxy l -containing starch )was prepared by crosslinking w ith epichlo rohy drin , followed by g raft ing w ith acrylonit rile , and base saponif icat ion to convert nitrile group into a mixture of carboxy amide and carboxy late groups .FeSO4 -H2O2 or (NH4)2Ce (NO3)6 was used as an initiator for graft polymerization .The so rption properties of carboxy l -containing starch for Cr3+ and Cd2+ heavy metalions have been studied in different crosslinking and graf ting conditions. The basis was also provided for its application
