Adsorption of ibuprofen using activated carbon derived from Dillenia Indica peels

Abstract

Abstract Adsorption of ibuprofen (IBP) onto a low-cost activated carbon, prepared at a laboratory scale from Dillenia Indica peels, has been investigated. The effect of initial ibuprofen concentration (20-100 mg/L) was studied. The equilibrium data obtained at 30 °C were analyzed by isotherms and kinetics study. The Langmuir and Freundlich isotherms were used to explain the experimental data. While pseudo-first-order and pseudo-second-order models were applied for adsorption kinetic at different initial concentrations of ibuprofen. It was found that the adsorption process obeyed Freundlich isotherm and pseudo-second-order kinetic model. The activated carbon presented adsorption capacities of 7.5075 mg/g.
