Vegetation Description and Analysis

Organically polluted waters are purified by contacting with a solid copper-manganese-oxygen catalyst promoted with bismuth under oxidizing conditions. In one preferred embodiment, an aqueous stream obtained from the effluent of an oxidative dehydrogenation process containing contaminating oxygen-containing organic materials is subjected to oxidizing conditions in the presence of a copper-manganese-bismuth-oxygen catalyst to convert the water to an aqueous product.
