Scope

This document describes the determination of the copper and cuprous oxide content in compound copper oxide powder by potassium permanganate titration, and the method of calculating the copper oxide content by subtraction. This document is suitable for the determination of the three components (namely, copper-cuprous oxide-copper oxide, also known as Cu-Cu2O-CuO) in compound copper oxide powder (i.e., compound copper-based materials, organic silicon methyl, and phenyl monomer synthesis copper-based catalytic materials).
