Abstract

In the present study, the parameters, temperature, adsorbent dose, contact time, adsorbent size and agitation speed were optimized for Methyl violet removal from aqueous medium by using response surface methodology (RSM). The optimum conditions for maximum removal of Methyl Violet from an aqueous solution of 100 mg/L were found as follows: room temperature (33 degrees C), adsorbent dose (500mg), contact time (180 min), adsorbent size (250 meshes) and agitation speed (200 rpm). Adsorption kinetic data were tested using Intraparticle diffusion model and Elovichâ€™s equation. Kinetic studies showed that the adsorption follows first order reaction. Studies revealed that the intraparticle diffusion plays an important role in the mechanism of dye adsorption.
