REMOVAL OF MALACHITE GREEN DYE FROM AQUEOUS SOLUTION BY ACTIVATED CARBON PREPARED FROM WASTE BIOMASS

Abstract

Adsorption of Malachite Green (MG) on activated carbon obtained from Azadiratcha indica has been investigated by batch adsorption method. The percentage removal of dye has been optimized by studying the initial concentration of the dye, adsorbent dosage, adsorption time and pH. The experimental data were found to be well fitted to Langmuir isotherm. Among the various kinetic models described, the adsorption of MG can best be described by the Lagergren first order kinetic model. The present study indicates that activated carbon obtained from Azadiratcha indica is an effective adsorbent of MG dye.
