Abstract

Studies on the removal of zinc by adsorption on two types of flyashes, namely Bokaro Thermal Power Plant Fly ash and Fluidized Bed Combustion Fly Ash from Tata Steel, Jamadoba were carried out. Since industrial waste water often contains high concentration of heavy metals/toxic elements, it was thought worthwhile to initiate studies on removal of these elements by adsorption on untreated flyash obtained from different thermal power plants be it pulverized coal fired or fluidized bed combustion. The first amongst them was zinc ions. Both the fly ashes were characterized and the analytical data indicated that these resembled with those obtained form bituminous coal. The aim of this work is to investigate the efficiency of these untreated fly ashes for the removal of zinc ions (ZN + +) from its aqueous solution. Batch adsorption experiments were done. The effects of various parameters such as contact time, initial concentration, pH, fly ash dosage on the removal of zinc ions were studied. It was found that zinc adsorption. Is favored in alkaline medium.
