EFFECTIVE REMOVAL OF TEXTILE DYES USING PRE-TREATED NATURAL ADSORBENTS

Abstract

Water contamination due to textile industrial discharge is one of major problems of modern world. Azo dyes are major culprits of water pollution due to presence of complicated azo bond. Synthetic wastewater with high concentration of azo dyes has been treated using different adsorbents in this study. This exploration technique is proved to be conservative, appealing and compelling for the removal of dyes from wastewater. In this investigation, pre-treated sugarcane bagasse and chicken eggshell were utilized as an adsorbent for adsorption of azo dyes from wastewater. All the experiments were allowed to run for 160 minutes. These adsorbents satisfactorily served the purpose of application. Eggshells and sugarcane bagasse and presented 79% and 73% removal of reactive red-1 respectively. Removal of direct blue-1 was observed as 96% and 95% using eggshells and sugarcane bagasse respectively.
