Abstract
A metallic ion sorber capable of absoring ions of a metal excluding iron and cobalt and a method of sorbing ions of a metal excluding iron and cobalt are disclosed. The sorber comprises an ethylene copolymer containing from 40 to 95% by weight of ethylene and from 5 to 60% by weight of at least one of aminoalkyl acrylate compounds represented by formula: ##STR1## wherein R.sub.1 represents a hydrogen atom or a methyl group; PA0 R.sub.2 and R.sub.3 each represents an alkyl group having from 1 to 4 carbon atoms; and PA0 n represents an integer of from 1 to 4, and having a number average molecular weight of from 5,000 to 50,000.
