Adsorption Isotherm of Fly Ash for Textile Dying Industry Effluents

Abstract

Textile industry effluents are highly toxic in nature and they contains a large number of complex metal dyes. Thus removal of colour from industrial dye effluents is a most perplexing problem to the industry . In this work Fly ash obtained from Kolaghat Thermal Power station (West Bengal) is used to study the potentiality of fly ash as a cheaper dye adsorbent. About 88% removal of colour (Malachite Green) was achieved using fly ash. The effect of temperature on adsorption has been studied. Applicability of Langmuir and Freundlich isotherm for this system has been investigated. An attempt has also been made to find out the rate constants from the experimental results
