Zusammenfassung:PURPOSE:To enable the preservation of an aq. H2O2 soln. over a long period of time without lowering the concn. by adding a specified chelating agent thereto. CONSTITUTION:A chelating agent having two or more sulfonic acid groups and/or salts thereof, e.g. pentasodium aminotri(methylenephosphonate) is added to an ag. H2O2 soln. having 1-90wt.% concn. by 1-1,000ppm or a pH adjusting agent such as a phosphate or borate, an isotonic agent such as NaCl and a stabilizing aid such as sodium silicate are further added as required.
