ADSORPTION KINETICS ON REMOVAL OF CHROMIUM FROM WASTEWATER USING ACACIA NILOTICA WOOD BASED ACTIVATED CARBON

Adsorption Capacity for the elimination of Chromium from the waste water has been studied from wood of Acacia Nilotica based activated carbon through various batch adsorption experiments .The adsorption kinetics of chromium using wood of Acacia Nilotica was done by differing factors such as amount of carbon added , pH and concentration levels of Chromium in wastewater. It was observed that the optimum dosage of wood of Acacia Nilotica based activated carbon to remove 80 mg/L of chromium from aqueous solution was 0.4gms/150 mL ,and the optimum contact time was 20 minutes. The isotherm data was found to be fit with both Langmuir and Freundlich isotherms.
