以硫醚为主链的螯合树脂研究——Ⅲ.含硫氰酸根树脂的合成及吸附性能

摘要: 环硫氯丙烷的均聚物或环硫氯丙烷与环氧氯丙烷的共聚物,在少量二乙烯三胺存在下制得预交联聚合物,将后者与硫氰化钾反应,制得两种侧链带有硫氰酸根的新型螯合树脂。它们对贵金属具有优良的吸附性能和高的吸附选择性。通过X射线光电予能谱初步探讨了树脂对金属离子的螯合作用

Abstract: The chelating resins(CTC, CETC) bearing thiocyemate groups were first synthesized by the reaction of polychloromethylthiirane (PCMT) or copolymer containing chloromethylthiirane and epichlorohydrin(PCMT-ECH) with potassium thioeyemate by using diethylenet
