Application of Clinotptilolite in Removal Ofnickel (II) in Plating Wastewater

The ability of Clinoptilolite powder to adsorb Ni (II) ions from wastewater which was taken from a nickel plating factory was investigated through batch experiments. The Ni (II) adsorption was found to be dependent on mass of adsorbent, contact time, pH value of solution and the speed of agitation. The experimental isotherms data were fitted into Langmuir and Freundlich models. The monolayer adsorption was determined since the data were best fitted to the Langmuir isotherm. The kinetic process of Ni (II) adsorption on Clinoptilolite powder obeys pseudo-second order rate. The Clinoptilolite powders investigated in this study exhibited a high potential for the removal of Ni (II) from nickel plating wastewater.
