Abstract

Rice husk is a waste material that potentially be used as a low cost adsorbent in wastewater treatment. Hence, the removal of malachite green dye from aqueous solution by basic modified rice husk was studied in the batch adsorption experiment. The Langmuir and Freundlich isotherms were applied to identify the adsorption type. At equilibrium time, the Langmuir isotherm model was fit rather than the Freundlich isotherm. The maximum monolayer adsorption capacity was found to be 151.51 mg g-1. Kinetic analysis showed that the sorption kinetic of malachite green by basic modified rice husk obeyed the pseudo-second order sorption. According to the whole study, the basic modified rice husk had a potential to be an alternative adsorbent to remove the hazardous malachite green.
