Abstract

PURPOSE:To obtain chemically stable titled resin capable of selectively adsorbing only mercury ion without influenced by coexisting salts, by carrying out a reaction in a specific condition between a halogen-contg. resin and special compound. CONSTITUTION:The objective resin can be obtained by carryng out a reaction, in a solvent such as dioxane at 90-110 deg.C for at least 1hr pref. 12-48hr, between (A) a halogen-contg. resin (pref. prepared by chloromethylation of a gel- or large network-type polystyrene-divinylbenzene copolymer), and (B) a solution containing salicylamine or 2-thenylamine in such amount as to be at least one gram molecule per gram atom of the chlorine in the component (A).
