Textile industries produce large amounts of waste water. Presence of various dyes like reactive dyes, azo dyes,
anthraquinone dyes, etc.is noted in textile industry effluent. In this work we intend to target azo dyes and anthraquinone dyes
which has various colouring and toxic effects. Literature review shows that there are various sustainable wastewater treatments
namely adsorption, electro-coagulation, ultrasonic treatment, etc. The present investigation intends to discuss the adsorption
method for the treatment of industrial wastewater using metal oxide nanoparticles.
