Apparatus and methods of providing diatomic oxygen (O
Methods of generating oxygen (O 2 ) are described in which ferrate(VI) is combined with an acid.
1. An oxygen dispenser, comprising:
a first compartment comprising ferrate(VI);
a second compartment comprising water in the presence of an acid, wherein the amount of the acid in the second compartment in comparison to the amount of the ferrate(VI) in the first compartment is such that there is a stoichiometric molar excess amount of acid in a range of 0 to 100%; and
a respiratory apparatus; wherein when in use, the ferrate(VI) in the first compartment is combined with the water and acid in the second compartment to generate oxygen for breathing applications, resulting in an aqueous composition having a pH in the range of pH 1 to pH 8.
2. The dispenser of claim 1 , wherein the respiratory apparatus comprises a mask adapted to be worn on the face of a person.
3. The dispenser of claim 1 or 2 , wherein the respiratory apparatus comprises a nasal mask.
4. The dispenser of claim 1 , wherein the first and second compartments are separated by a breakable wall.
5. The dispenser of claim 1 , wherein the amount of the acid in the second compartment in comparison to the amount of the ferrate(VI) in the first compartment is such that there is a stoichiometric molar excess amount of acid in a range of 0 to 50%.
6. The dispenser of claim 1 , wherein the acid comprises a carboxylic acid that does not have an alpha hydrogen, a phosphoric acid, a polymeric acid, a sulfonic acid, a sulfuric acid, a ferric ion salt, an aluminum ion salt, a zinc ion salt, a silicic acid, a phosphonic acid, or a blend or mixture of thereof.
7. The dispenser of claim 1 , wherein the acid comprises a solid acid ion exchange resin.
