MIXED BED ION EXCHANGE RESIN COMPRISING ANION EXCHANGE RESIN AND CATION EXCHANGE RESIN, METHOD FOR PREPARING THE SAME AND METHOD FOR PURIFYING HYDROGEN PEROXIDE SOLUTION USING THE SAME

摘要

The present invention relates to a mixed-phase ion exchange resin comprising an anion exchange resin and a cation exchange resin, a method for producing the same, and a method for purifying hydrogen peroxide water using the same, and more particularly, to an alkali metal complex of stannous oxide adsorbed, Including an anion exchange resin converted to a bicarbonate ion type or an anion exchange resin converted to a carbonate ion type and bicarbonate ion type, and a cation exchange resin converted to a hydrogen ion type to which a chelate compound is adsorbed, the precision electronics industry among aqueous solutions of hydrogen peroxide It relates to a mixed-phase ion exchange resin capable of producing ultra-high purity hydrogen peroxide used in the field (especially for manufacturing high-density semiconductor substrates, etc.), a method for producing the same, and a method for purifying hydrogen peroxide solution using the same.
