Title

Adsorptive removal of Crystal Violet from aqueous solution by Kokum (Garcinia Indica) leaf powder: Equilibrium and Thermodynamic studies

Abstract

In this paper, adsorptive removal of Crystal Violet dye from aqueous solution using kokum leaf powder was carried out in batch process. The effect of contact time, adsorbent dose, pH, initial concentration and temperature have been studied. The linear regression coefficient R2 was used to evaluate the best fitting equilibrium isotherm model. Experimental data were best fitted by both Langmuir and Freundlich isotherm models. From the experimental data, it was found that maximum monolayer adsorption capacity of kokum leaf powder was found to be qm = 109.89 mg/g. The pH of solution is an important factor to control the dye adsorption. The adsorption of Crystal violet dye increases with increase in pH and increase in temperatures. The values of RL and thermodynamic analysis indicated that adsorption was spontaneous, endothermic and favorable and increased randomness during adsorption of Crystal violet on Kokum leaf powder. Thus Kokum (Garcinia Indica) leaf powder was found to have effective adsorption capacity for the removal of Crystal violet dye from aqueous solution
