Experimental investigation was carried out by using commercially available husk of green gram (phaseolusaureus) seed to removal ofmethylene blue from aqueous medium. Husk of green gram seed was characterized by performing particle size distribution. The effect of contact time, effect of initial concentration of dye, effect of dosage, effect of salt, effect of pH, zero point pH and effect of temperature were studied in batch technique. Adsorption kinetic was verified by pseudo-first-order and pseudo-second-order models. The rate of adsorption of methylene blue followed by pseudo-second-order model for the dye concentration studied in the present case. Adsorption of methylene blue on green gram (phaseolusaureus) seed husk is also followed by Langmuir and Freundlich adsorption isotherm.
