ADSORPTION OF Cu(II) IONS FROM AQUEOUS SOLUTION USING MICROWAVE ASSISTED PTEROCARPUS MARSUPIUM BARK CARBON

Abstract

An effective adsorbent was prepared from bark of Pterocarpus Marsupium tree and its various adsorption characteristics were studied for removal of Cu(II) ions from aqueous solution. Optimized conditions for the preparation of effective activated carbon were found to be microwave radiation power 850W, radiation time 15 min, 50% of ZnCl2 and impregnation time 24 hours. Batch mode adsorption experiments were carried out. Influence of the parameters such as Dose of the adsorbent, agitation time, initial dye concentration, pH of the solution and temperature on adsorption were studied. Kinetics of the system was studied with linearised forms of Lagergren, Ho and Webber Morris model s. Equilibrium data were fitted with Langmuir and Freundlichisotherms. The order of best describing isotherms was given based on R2 value.
