In a landmark development for the food packaging industry ... scavengers typically employ synthetic chemicals such as potassium permanganate that can pose health and environmental risks.

The ordinary macro-Kjeldahl method was much improved in speed and reliability by using a mixed selenium–mercury catalyst with the usual potassium sulphate; but even in this case some doubt ...

This process is sped up by a catalyst. In this reaction, the catalyst is potassium permanganate, and the bubbles are full of oxygen gas. Hydrogen peroxide decomposes on its own into water and oxygen ...
