Abstract: The fixed bed of sodium carbonate treated rice husk (NCRH) was used for the removal of Zn(II) from water environment. The NCRH was found to be a efficient media for the removal of Zn(II) from wastewater. The column having a diameter of 2 cm, with bed depth 10 cm can treat 2.28 litre of Zn(II) bearing wastewater with Zn(II) concentration 10 mg/l and flow rate 9.5 ml/min. A method has been shown to predict the theoretical breakthrough curve using the data obtained from the batch isotherm studies and theoretical breakthrough curve was compared with experimental breakthrough curve.
