The aim of the present work was to investigate the feasibility of Kattamanakku tree leaf powder carbon (KTC) for Acid Red-114 (AR-114) adsorption. The adsorption of AR-114 on KTC material was studied as a function of KTC dose (0.05-1.20g). , solution pH 3-10, contact time and initial concentration (70-380 mg/l)., The influence of these parameters on the adsorption capacity was studied using the batch process. The experimental data were analyzed by the Langmuir and Freundlich isotherms. The adsorption isotherm was found to follow the Langmuir model. The monolayer adsorption capacity was found to be 450.02 mg/g. The kinetic data were fitted in the pseudo-first order and pseudo-second order models and were found to follow closely the pseudo-second order kinetic model. The results revealed that KTC adsorbent is potentially low cost adsorbent for adsorption of AR-114.
