Definitions
- This invention consists in improved metallic media for the fixation of the oxygen of water in apparatus for abstracting gases from li uids. g
- the xation of the oxygen dimolved in water is brought about in apparatus for ab- 2 stracting gases from liquids by the chemical combination of this oxygen with iron filings and turnings, and is represented by the to lowing chemical reactions:
- he manganese acts as a catalyst in the oxidation and combines instantaneously with the oxygen, yielding oxide of iron and protoxide of manganese, MnO, capable of oxidizing in turn into dioxide and sesquioxide, which can be reduced again by the iron.
- MnO protoxide of manganese
- the proportion of manganese most favourable for'the catalysis is over 5% of the weight of the metal and below 6% of the weight of the iron.
- the speed of reaction [0 is proportional to the quantity of man, ganese employed and inversely proportional to the quantity of-carbon in t e metal.
