General description

Calcium peroxide (CP) is a peroxide compound that releases oxygen and hydrogen peroxide. It is a safe inorganic peroxy compound in a solid form of oxygen. It can be used in the remediation of contaminated sites. It has the ability to construct a permeable reactive barrier system by acting as oxygen releasing material (OSM).

Application

CP can be used as an amendment that facilitates the supplying of oxygen for agriculture, horticulture and biotechnology applications.
