Oxidation of Azo Dyes with Inorganic Peroxides in the Presence of Cationic Surfactants

摘要

Degradation of Direct Red 23,Rective Red 45,and Orange II azo dyes with hydrogen peroxide and hydroperite in the presence of cationic surfactants alkyldimethylbenzylammonium chloride(Katamin AB)and cetyltrimethylammonium chloride and without them was studied by spectrophotometry.The reactivity of the azo dyes was correlated with their chemical structure.
