Biodecolorization of basic dyes using Ecofriendly low cost adsorbents

Abstract

Dyes are organic colorants used in several industries including newlinetextile paper leather food and cosmetic Wastewater discharged from these newlineindustries often comprise of residual dyes in various concentrations The newlinepresence of dyes in the watercourse through effluents is aesthetically newlineundesirable as well as leads to serious environmental impact Various newlinetechniques have been employed for the treatment of dye containing newlinewastewaters including physical chemical biological methods and newlinecombinations of the above Among the various methods available biosorption newlineof textile dyes by nonliving biological materials is a highly costeffective and newlinenew alternative process for the decontamination of dyecontaining effluents. newlineBasic dyes are predominantly used in coloring acrylic fiber that are generally newlinemore toxic than other classes of dyes and these are the brightest class of water newlinesoluble dyes used by the textile industries. Presence of this dye in water leads newlineto various health effects to humans and affects the aquatic system and newlineenvironment newline newline
