<P>PROBLEM TO BE SOLVED: To provide a non-agglomerating mixed bed ion exchanger. <P>SOLUTION: This method for producing a non-agglomerating mixed bed ion exchanger is characterized by treating an anion exchange component with one or more aromatic sulfonic acid condensation product in an application concentration of 10 to 100 g/liter (resin) before or after mixed with a cation exchange component. The aromatic acid is preferably phenol sulfonic acid, sulfonated ditolyl ether, 4,4'-dihydroxydiphenyl sulfone, sulfonated diphenylmethane, sulfonated biphenyl, sulfonated terphenyl, naphthalene sulfonic acid, or benzene sulfonic acid. <P>COPYRIGHT: (C)2008,JPO&INPIT |
