Useful:

• Uses: Sodium persulfate is used as a bleach, both standalone (particularly in hair cosmetics) and as a detergent component. It is a replacement for ammonium persulfate in etching mixtures for zinc and printed circuit boards, and is used for pickling of copper and some other metals. It is a source of free radicals, making it useful as an initiator for e.g. emulsion polymerization reactions and for accelerated curing of low formaldehyde adhesives. Sodium persulfate is also used as a soil conditioner and in manufacture of dyestuffs, modification of starch, bleach activator, desizing agent for oxidative desizing, etc. For waste processing in the photographic industry, used as a soft metal surface corrosion agents of the printed circuit board and textile desizing agents, sulfur dyes colorformer. Bleaching and oxidizing agent; promoter for emulsion polymerization reactions. Sodium peroxydisulfate is used as a radical initiator for emulsion polymerization reactions like acrylonitrile butadiene styrene, detergent component, soil conditioner and soil remediation. It is also used for curing of formaldehyde adhesives. It acts as a bleaching agent and in the production of dyestuffs. It finds application in zinc and printed circuit boards and considered to be a replacement for ammonium persulfate in etching mixtures. Further, it is used in the preparation of diapocynin from apocynin. It plays a role in the conversion of phenols to para-diphenols in alkaline solution and of arylamines to aminophenols. It is actively involved in the Elbs persulfate oxidation and the Boyland-Sims oxidation reactions as an oxidizing agent.
