Abstract | The organic materials responsible for color in water have been isolated from several natural streams and subjected to comparative chemical studies. Oxidation with alkaline-CuO was found to be an effective method of degrading the complex color molecule to recognizable chemical structures. Seven degradation products of natural organic color were identified; namely vanillin, vanillic acid, syringic acid, catechol, resorcinol, protocatechuic acid and 3,5-dihydroxy-benzoic acid. Evaluation of the effect of the oxidation technique on model compounds coupled with the knowledge of seven color degradation products resulted in the proposal of a structural formula for color producing molecules in water.
