摘要
报道三种酚醛冠醚聚合物对水溶液中某些金属离子的吸附性能。这类中性络合树脂动态吸附容量在０．００１～０．１５４ｍｍｏｌ／ｇ之间，并对Ａｇ~＋－Ｎｉ^（２＋）等有较好的选择性。
he paper describes a new method of adsorbing and separating trace rnetallic ions from water with several kinds of phenoladehyde polymeric crown ethers. Their adsorbing capacities,adsorbing and separating effects have been inverstigated. The adsorbing efficiency of polymeric crown ethers for K+、Ag+、Cu2+……(10(-6)～10(-4)mol/L) is up to 60%～90%, and the adsorbing capacties of polymers to silver are about 0. 154 mmol/g resin.
