Defines a procedure for the determination of cadmium and zinc either in paper or in highly opaque pigments. Zinc is usually present in zinc oxide, zinc sulfide, or as lithopone (a combination of zinc sulfide and barium sulfate), which is occasionally used in filled paper, in paper coatings and in high-pressure laminates and wallpaper.
