OPTIMIZATION OF ADSORPTION PROCESS FOR REMOVAL OF SULPHONATED DI AZO TEXTILE DYE

Abstract

Treatment of textile waste water has emerged as a great matter of concern amongst scientific community because of essentiality and scarcity of this valuable natural resource. Various techniques have been employed for waste water treatment, amongst which use of natural materials have made a significant contribution in the area of sustainable environment.This paper focuses on the use of the seeds of Argemone Mexicana, a weed for removal of a textile dye from its synthetic solution. Optimisation of several parameters has been carried out for elimination of dye from water resource at neutral conditions. Variation in different parameters affecting decolorization of the dye from aqueous solution, have been studied at length. Maximum decolorization (About 60%) has been observed after four hours with 0.1 g of the elected natural adsorbent obtained after passing through sieve size of 300 µm.
