- Abstract
The sorption potential of either peanut hull or fly ash to decolourize the aqueous solution of methylene blue (MB) was investigated at room temperature. Many operating variables were studied in a batch technique. Of these, solution pH, dosage of the used sorbent biomass, initial dye concentration and the applied contact time. The resulting data was fitted and was more suitable by Langmuir isotherm model than the Freundlich one confirming the formation of monolayer from the sorbed dye on the sorbent sur-face. All parameters of Freundlich and Langmuir were calculated from the experimental results. The transient behaviour of the batch sorption process at different initial MB concentration was analyzed utilizing Lagergren pseudo first-order kinetic model and Ho and McKay pseudo second-order model.
