ANION EXCHANGER MIXTURE OF ANION EXCHANGER AND CATION EXCHANGER MIXED BED COMPRISING ANION EXCHANGER AND CATION EXCHANGER PRODUCTION PROCESSES THEREFOR AND METHOD FOR PURIFYING AQUEOUS HYDROGEN PEROXIDE SOLUTION

摘要

The anion exchanger (B) is contacted with the carbon dioxide soluble water obtained by dissolving carbon dioxide gas in pure water or ultrapure water to the mixture of the anion exchanger (B) and the cation exchanger to convert the anion exchanger (B) into a bicarbonate ion type or bicarbonate ion type, Wherein the anion exchanger (A) having the anion exchanger (A) and the anion exchanger (A) having the anion exchanger (A) /RTI According to the present invention, an anion exchanger in a mixture of an anion exchanger and a cation exchanger can be converted into a bicarbonate ion type or a bicarbonate ion type and a carbonate ion type while remaining in a mixture state.;
