The demand for activated carbon is increasing owing to the increased utility of the carbonrnmaterials in pollution control. As a result, cost of activated carbon is also growing depending onrnthe application. Designing ways for the production of activated carbon through economic ways isrnthe need of the hour. A range of low cost, easily available, carbon rich and low ash precursorsrnand sources are being explored for the production of carbon materials. This research hasrnpresented sesame (Sesamum indicum) husks as row material for preparation of low cost activatedrncarbon and assessed its potential application for adsorption of Cr(VI) from aqueous solution.rnProcess variables for sesame husk activated carbon preparation were optimized response surfacernmethodology (RSM). The effect of activating agent concentration, impregnation ratio,rncarbonization temperature and holding time were analyzed as main factor variable based onrnBBD. Adsorption % of Cr(VI) was used as response variable. The statistical significance of thernmodel was investigated by ANOVA. The optimum condition during sesame husk based activatedrncarbon preparations was found 30min, 614.70C, 1M, 1w/w and 76.41 for holding time,rnCarbonization Temperature, Concentrations of Activating agent, Impregnations Ratio andrnAdsorptions % respectively at pH 2, amount of adsorbent dosage of 0.5g in 100mL solutions andrntemperature of 250C. Characterization result shows sesame husk can be used as row material forrnproductions of activated carbon with comparable property with other reported activated carbons.rnThe optimum pH value for the adsorptions of was determined to be 2, at which the Cr(VI)rnremoval of were determined to be approximately 76%. The uptake of chromium from solution byrnSHAC increased with contact time and attained equilibrium at 360min for all of the temperaturesrnstudied. The adsorptions kinetics of pseudo-first order and pseudo-second-order rate equationsrnwere tested on the kinetic data and the adsorptions process was found to follow pseudo-secondorderrnrate kinetics for all temperature. The Langmuir and Freundlich isotherm models werernapplied to the experimental equilibrium data depending on temperature at 30, 40 and 50oC, andrnthe isotherm constants were determined by using linearized correlations coefficient. Equilibriumrndata were represented better by the Freundlich model than the Langmuir model. Freundlichrnequations was found to fit the equilibrium data for Cr(VI) adsorption with monolayer capacity ofrn18.34, 17.54 and 16.01 at 30, 40, and 500C respectively.
