Calcium peroxide (CaO2), as one of the solid peroxides, has been increasingly used in contaminated site remediation due to its ability to release oxygen (O2) and hydrogen peroxide (H2O2). Biodegradation can be enhanced by the existence of O2. Hydrogen peroxide can be used to for in situ chemical oxidation via the modified Fenton. Previous studies show inconsistent results about O2 and H2O2 release during CaO2 decomposition.
Calcium peroxide is a solid chemical used as a source of oxygen or hydrogen peroxide. When placed in water, calcium peroxide begins to decompose and release oxygen. When treated or dissolved in acids, calcium peroxide forms hydrogen peroxide. Calcium peroxide is a pale yellow, granular or powdered solid oxidizer. Exposure to calcium peroxide can cause irritation to the skin, eyes, and respiratory tract.
Ingestion should be avoided at all concentrations. Calcium peroxide is not persistent in the environment and slowly decomposes to form calcium hydroxide and oxygen.
