eng Photocatalytic Treatment of Indigo-6,6?-Dicarboxylic Acid We present kinetic model of heterogeneous photolysis based on Langmuir-Hinshelwood adsorption isotherm and photochemical reaction on the surface of catalyst. Indigo-6,6?-dicarboxylic acid was used as a model substance. Photolysis was studied in aqueous suspension of TiO2 buffered with sodium bicarbonate. Langmuir?s adsorption constant was determined.
