To removal of toxic metals from aqueous solution is the primary substantial issue for many industries. Adsorption of Ni and Cu ions onto a non-conventional plant biosorbents, Pungan Leaf Powder was investigated in batch adsorption experiments. Process parameters which include pH, adsorbent dosages and contact time were varied in order to evaluate their influence on the adsorption process. The results obtained indicate that the adsorption of Cu on Pungan Leaf Powder is better than Ni. Besides that, the adsorption of Cu(II) on Pungan Leaf Powder was found to fit the Freundlich isotherm The effective removal of nickel and copper from textile wastewater is studied using Pungan Leaf Powder.
