Oxone™ Potassium Monopersulfate

If strong oxidiation is needed, Oxone™ monopersulfate is the right choice for a wide variety of industrial and consumer application. It is a peroxygen chemistry with a 4.7% active oxygen content that is a powerful oxidant (1.85V) without the presence of chlorine.  It is soluble in water and is fast dissolving.  It is also soluble in methanol, ethanol, acetone, DMF, ionic liquids and solvents like Phase Transfer Catalysts like dichloromethane, ethylacetate, and toluene. ChemPoint partners exclusively with LANXESS Corporation on the white, granular, free-flowing powder form.

Metal Surface Preparation
 
Oxone™ is a free-flowing powder chemical microetchant for electronics and printed wiring board manufacturing industries. Other benefits include: free-flowing powder, high etch rates that are uniform and predictable, excellent bonding morphology, well-defined surface topography, contaminant removal, high rinsability, long bath life with simple analysis and control, better performance at lower temperatures, and allowing for energy and cost savings.

Metal Finishing & Hydrometallurgy

Oxone™ (KPMS) is also used in direct and indirect oxidation techniques in metal extraction, ore separation, hydrometallurgy, and other surface treatments of metals and metal alloys like alloy formation, lamination, copper plating, final finish, and flash etch. It functions for the destruction of cyanides as well as the oxidation of the various metals, including Chromium, Copper Sulfide, Chalcopyrite, Cobalt, Nickel, and Manganese.

In non-ferous metal finishing applications, Oxone™ finds application in etching or microetching surfaces to reduce thickness, removal of oxidation layers and pre-clean prior to metal bonding or plating.

Environmental Waste Streams

Most widely used in the oxidation of cyanide, reduced sulfur, and amine compounds, Oxone™ provides safety and convenience in handling. In oxidizing hydrogen sulfide (H₂S) in waste streams, KPMS allows for deodorizing a waste stream or stack via scrubbing without on-site manufacture or handling of hazardous ingredients like Caro's acid. Analytical testing is still required to determine the effect on the waste stream to ensure complete removal of all compounds, including mercaptans, sulfides, disulfides, and sulfites.  

For metal plating or mining operations where the removal of cyanide is needed, Oxone™ can rapidly oxidize cyanide much more quickly than hydrogen peroxide, sodium percarbonate, sodium perborate, or sodium dipersulfate.  Particularly in dilute or small waste streams, Oxone™ based processes are convenient and economical - it is easy to transport and store Oxone™ compared to hydrogen peroxide, sodium percarbonate, sodium perborate, peracetic acid, sodium dipersulfate, chlorine, hypochlorite, or ozone which cannot be transported at all.

Switching away from chlorinated oxidizers
Low concentration and byproducts of chlorinated oxidizers
Oxidizer label required when using traditional oxidizing agents in the formulation
Low solubility of solid form oxidizers in hard water and at low temperatures
No control over etching rate in the production of electronics and micro-electronics
Algae bloom (turn dark or green) in pool and spa applications
Blockage and frequent cleaning of felts in paper mills
Inadequate or insufficient bleaching in denture cleansers, textiles, and cleaning applications
