PROBLEM TO BE SOLVED: To provide a preparing method of a non-coagulative mixed bed ion exchange resin system without affecting the ion exchange speed of an anion exchange resin component of the mixed bed system. SOLUTION: A treating method in which the anion exchange resin component is pre-treated with a sulfonated poly(vinyl arom.) high molecular electrolyte is especially effective for providing the non-coagulative mixed bed system without affecting the ion exchange speed. A loading of 10-800mg sulfonated poly(vinyl arom.) high molecular electrolyte having a number average mol.wt. of 5,000-1,000,000 to 1l of the anion exchange resin is especially preferable. |
