Abstract: An iminodiacetic acid type chelate resin which can be easily and efficiently produced and which can efficiently adsorb and separate metal ions; and a method for producing the same are developed. The use of a chelate rein having a carboxymethyl group introduced into primary amino groups of the polyvinylamine crosslinked polymer particles can facilitate the efficient adsorption and separation of metal ions in water. The chelate resin can be obtained by a production method in which an N-vinyl carboxylic acid amide is suspension polymerized with a crosslinkable monomer in salt water in the presence of a dispersant thereby to obtain a polyvinyl carboxylic acid amide crosslinked polymer particles, and the obtained polyvinyl carboxylic acid amide crosslinked polymer is hydrolyzed to thereby introduce a carboxymethyl group into primary amino groups of the polyvinylamine crosslinked polymer particles.

Abstract: In an ion-exchange separation system, a single regeneration column provides for separation of anion and cation resins and the regeneration of both cation and anion resins with a very low level of cross-contamination. After regeneration most of the anion layer in the column is withdrawn, and most of the cation layer is withdrawn, but a portion of each layer adjacent to the interface between the layers remains in the column, to isolate these cross-contaminated portions from the regenerated resins. The withdrawn, regenerated anion and cation resins are placed back into the working vessel.
