Abstract
Abstract: 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. Literature review supports the use of synthesized porous MgO powder at Nanoscale for the removal of dyes from aqueous solution. Results indicate that the MgO powder can remove more than 98% of both dyes under optimum operational conditions. At various MgO dosages, dye concentrations, solution pH and contact time in a batch reactor are studied. The analysis is followed by FTIR & XRD.
