TREATMENT OF METAL SURFACE

PROBLEM TO BE SOLVED: To obtain a stabilizer for stabilizing an acidic aqueous solution of hydrogen peroxide for treating metal surface. SOLUTION: This stabilizer contains (a) hydroxybenzoic acid, preferably p-hydroxybenzoic acid, (b) a hydrotropic arylsulfonic acid, preferably p- toluenesulfonic ac...

Zusammenfassung:	PROBLEM TO BE SOLVED: To obtain a stabilizer for stabilizing an acidic aqueous solution of hydrogen peroxide for treating metal surface. SOLUTION: This stabilizer contains (a) hydroxybenzoic acid, preferably p-hydroxybenzoic acid, (b) a hydrotropic arylsulfonic acid, preferably p- toluenesulfonic acid and (c) a hydrophobic alkarylsulfonic acid, preferably dodecylbenzene sulfonic acid at a weight ratio of (80-200):(50-120):(2.5-6). The stabilizer, most preferably, exists in a concentration of 3-10g/L in 35-70% aqueous hydrogen peroxide solution introduced into an acidic aqueous solution for treating a metal.
