Title:
IMINODIACETIC ACID TYPE CHELATE RESIN AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2017/126355
Kind Code:
A1
Abstract:
To develop: an iminodiacetic acid type chelate resin which is able to be easily and efficiently produced and is capable of efficiently adsorbing and separating metal ions; and a method for producing this iminodiacetic acid type chelate resin. Metal ions in water are able to be efficiently adsorbed and separated by using a chelate resin in which a carboxymethyl group is introduced into a primary amino group of polyvinylamine crosslinked polymer particles. This chelate resin is able to be obtained by a production method wherein polyvinyl carboxylic acid amide crosslinked polymer particles are obtained by suspension polymerizing an N-vinyl carboxylic acid amide and a crosslinkable monomer in salt water in the presence of a dispersant, and the polyvinyl carboxylic acid amide crosslinked polymer is subsequently hydrolyzed, thereby introducing a carboxymethyl group into a primary amino group of the polyvinylamine crosslinked polymer particles.
