Adsorption isotherm and kinetic study of Direct Orange 102 dyes on TNJ activated carbon

Abstract The present research shows an adsorbent prepared from an agricultural waste was studied for its efficiency in removal color. The process parameters were analyzed like agitation time, initial dye concentration, adsorbent dose, pH and temperature. The experimental data analysed by the Langmuir and Freundlich models of adsorption. The adsorption isotherm data were fitted well to Langmuir isotherm. The Kinetic data obtained at different concentrations were analysed using a pseudo first order and second order kinetic model. The experimental data fitted very well the pseudo second-order kinetic model. This study proves that the novel activated carbon is a promising adsorbent for remediation of textile effluent in a sustainable manner.
