Potassium Monopersulfate Compound

  • Potassium peroxymonosulfate (also known as MPS, potassium monopersulfate, potassium caroate, and the trade names Caroat and Oxone) is widely used as an oxidizing agent. It is the potassium salt of peroxymonosulfuric acid.

Potassium Monopersulfate Compound


Product Introduction

Potassium Monopersulfate Compound is a free flowing, white granular, and soluble in water (20℃, 256 g/L). The composition of Potassium Monopersulfate Compound includes Potassium hydrogen peroxymonosulfate(KHSO5), Potassium bisulfate(KHSO4) and potassium sulfate(K2SO4). Potassium Monopersulfate compound has relatively high redox potential. Therefor it is a highly effective oxidant and disinfectant.
