Potassium superoxide is the inorganic compound with the formula KO2. It is a
yellow paramagnetic solid that decomposes in moist air. It is a rare example of a
stable salt of the superoxide ion.
Detailed description
Potassium superoxide is used as a CO2 scrubber, H2O dehumidifier and O2 generator in rebreathers, spacecraft, submarines and spacesuit life support
systems.
Applications
The Russian Space Agency has had success
using potassium superoxide in chemical oxygen
generators for its spacesuits and Soyuz spacecraft. KO
2 has also been utilized in canisters for rebreathers for fire fighting and mine rescue work, but had limited use in scuba rebreathers because of its dangerously explosive reaction with water. The theoretical capacity of KO
2 is the absorption of 0.618 kg CO2 per kg of absorbent while 0.450 kg O
2 are generated per kg of absorbent. For one KO
2 molecule, it's one CO2molecule but only 0.75 oxygen molecules. The human body though will produce less CO2 molecules than oxygen molecules needed because oxidation of food also needs oxygen to produce water and urea.
