Potassium monopersulfate Circuit board etchant CAS NO.70693-62-8

1. Swimming Pool Shock and Spa

   Potassium monopersulfate can be added to pool water day or night, and swimming caroat, oxone, virkon can resume after a short waiting period to allow for adequate mixing and dispersion throughout the pool. No mixing is required; potassium monopersulfate is completely soluble in water and dissolves quickly. Broadcast monopersulfate shock slowly and uniformly over the surface of the water, adding about two-thirds of the total dose over the deep end. Shock with the filter running to ensure complete mixing and good circulation.Potassium monopersulfate is a versatile oxidant. It oxidizes aldehydes to carboxylic acids; in the presence of alcoholic solvents, the esters may be obtained. Internal alkenes may be cleaved to two carboxylic acids, while terminal alkenes may be epoxidized. Thioethers give sulfones, tertiary amines give amine oxides, and phosphines give phosphine oxides. It will also oxidize a thioether to a sulfone with 2 equivalents. With one equivalent the reaction converting sulfide to sulfoxide is much faster than that of sulfoxide to sulfone, so the reaction can conveniently be stopped at that stage if so desired.

   The advantages to use Potassium Monopersulfate in smimming pools treatment:

   • Maximum disinfection efficiency caused by oxidizing properties,
   • Restores water cleanliness and transparency,
   • Suitable for all types of swimming pools, spas, bathtubs,
   • Significantly improves chlorination efficiency through quick oxidization of organic contaminants,
   • Very quick action – facility is ready to use after 15 minutes,
   • Harmless to swimming pool surfaces, causes no bleaching or discolouration of painted and vinyl-coated surfaces,
   • No irritating odour, does not cause allergy as it contains no chloride, aldehydes, alcohol,
   • Has no impact on water hardness.

2. Microetching and cleaning of printed wiring/circuit board (PWB)

   For PWB industry, microetch solutions used to remove excess graphite and/or carbon black may be based on hydrogen peroxide or sodium persulfate as the oxidizing agent. For example, a sodium persulfate-based product may be combined with sufficient sulfuric acid to make a microetch bath containing 100 300 grams of sodium persulfate per liter of deionized water and about 1 to 10% by weight sulfuric acid. but nowadays, technical people find that potassium monpersulfe could be used as very good solution as it contains required oxideizer, sulfuric acid as one step solution.

3. Wool Shrinkproofing

   Potassium Hydrogen Persulfate is more commonly known name as an oxidizer for wool shrinkproofing treatment. It is in the form of a granule, easily dissolved, and an aqueous solution contains the dissolved oxidizer is stable for sotrage at a temperature of 32 centigrade. a -S--S-bond is stopped at substantially mono-oxidized state.

4. Odor control agent in wastewater treatment

5. Bleach component in denture cleanser and laundry formulations

6. Activator in antimicrobial compositions

7. Other uses where its combination of powerful oxidation and relative
