Transition metal ions have the ability to increase the oxidation performance of the inorganic peroxy salts at room temperature by possibly lowering their activation energy or by producing more reactive free radicals. When two transition metal salts are used togeher to decompose dipersulfate, it provides synergistic oxidati on activity, better than that obtained by dipersulfate or dipersulfate with either copper or zinc alone. The transition metals mentioned are the water soluble salts of copper and zinc. Oxidation performance of sodium dipersulface in presence of catalytic amou nt of copper and zinc salts was determined by measuring the dest ruction of crystal violet dye at a wavelength of 589 nm.
