Why is geography so important? Copper(I) oxide is found as the reddish mineral cuprite Once the copper chloride concentration gets right (see the copper chloride document on my website) the solution works really good with an occasional kick start of peroxide. The catalyzed kinetics of the oxidative mineralization of the cationic dye methylene blue, phenothiazonium, 3,7-bis(dimethylamino)-chloride, with hydrogen peroxide were studied both in buffered and unbuffered solutions.
