inorganic peroxide

[¦in·ȯr¦gan·ik pə′räk‚sīd]
(inorganic chemistry)
An inorganic compound containing an element at its highest state of oxidation (such as perchloric acid, HClO4), or having the peroxy group, ‒O‒O‒ (such as perchromic acid, H3CrO8·2H2O).

The particle size distribution of the inorganic peroxide was measured based on the formulated liquid paints.
For the former, clotting of the pores would limit the release rate during water immersion; and for the latter, the alkaline products developed during the reaction between water and the inorganic peroxide would increase the rate of hydrogen peroxide decomposition.
Antifouling based on inorganic peroxides has previously been described in two Japanese patents dating back to 1988 (3) and 1989.
Hydrogen peroxide can be generated by enzymatic reactions(7) or photo-catalytic reactions,(8) or it can be a product of a reaction between water and a suitable precusor compound such as inorganic peroxides.(9)
The reaction between inorganic peroxides and water yields hydrogen peroxide, molecular oxygen, or a combination thereof.

However, because hydrogen peroside is the compound intended to actively hinder fouling, we believe that hydrogen peroxide is the prime "biocide" and should therefore be registered if inorganic peroxides are intended for use in antifouling coatings.
The aim of this work has been to determine the potential of inorganic peroxides as active antifouling coating ingredients.
The binder constituents represent fast-, slow-, and intermeidate-poloshing antifouling coatings The experimental pigments were tested for coating compatibility, and formulated coatings were used to determine the performance of the inorganic peroxides in antifouling coatings in general.
The reaction between inorganic peroxides and water tends to result in oxygen as well as hydrogen peroxide.
The GPX enzyme works in tandem with CAT to remove hydrogen peroxide: CAT converts the hydrogen peroxide into molecular oxygen and water, while GPX uses reduced glutathione as an electron donor and catalyzes the biotransformation of various organic and inorganic peroxides [29].
