General description

Potassium chlorate (KClO3) is widely used in the chemical industry as an oxidizing agent. KCIO3 is used in the conversion of alcohols to corresponding aldehyde or ketone derivatives.

Application

Potassium chlorate is used:
  • In the sequential extraction (SEP) of selenium to analyze its isotopic composition from various Se pools.
  • In the preparation of graphite oxide (GO).
