Adsorption efficiency in removal of chromium from waste water has been studied using Derris indica based activated carbon by conducting batch adsorption tests. Adsorption kinetics of chromium removal by Derris indica was examined by varying factors such as pH and concentration of synthetic solution and dosage of activated carbon. It has been found that the Derris indica based activated carbon is able to remove 80 mg/dm3 of chromium from aqueous solution by dosage of 0.8 g/150 cm3 with optimum contact time of 15 min. The isotherm data confirms with both Langmuir and Freundlich isotherm forms.
