Synthetic dyes are widely used in industries. Various dyes such as methylene blue, azo dyes are used for various applications. The effluent containing dyes is a serious global problem because of its properties and toxicity. The removal and decomposition of dyes can be carried out by various chemical methods, oxidation, ozonation as well as photochemical methods. Adsorption is also effective way for dye treatment of wastewater. Various investigators have carried out investigation on dye removal and decomposition. Various aspects such as affecting parameters, isotherms and kinetics have been studied and the results have been reported. The current review summarizes the research and studies on dye decomposition and treatment for water containing dyes.

Key words: decolourization, kinetics, isotherm, oxidation, concentration.
