Removal of m-chlorophenol from Wastewater by Adsorption onto Flyash Produced from Thermal power plant: Kinetic Modeling Studies

Abstract

Adsorption technique is widely used for removal of toxic organics from aqueous solutions. As commercial activated carbon is an efficient adsorbent, it’s widespread used is restricted due to its high cost and substantial lost during regeneration. The aim of this study is to investigate the possibility of flyash (FA) as an alternative adsorbent for phenols removal from aqueous solution .The removal characteristics of m-chlorophenol (MCP) from aqueous solution by flyash is investigated under various conditions of contact time, particle size, pH, concentration and temperature. The level of uptake of m-chlorophenol by flyash decreased with increasing particle size and pH but increases with temperature. Rate constants for different conditions are evaluated using first-order kinetics. The experimental results underlined the potential of flyash for removal of m-chlorophenol from wastewater.
