The removal of nickel ions in wastewater by enhanced ultrafiltration and adsorption was studied. Nickel ions was firstly complexed with PAA (Polymer acrylic acid) to increase the molecular weight which was larger than the molecular weight cut-off (WMCO) of the ultrafiltration membrane. Then the nickel ions contained in the concentrated solution was removed by peat. The effects of pH, dosage of PAA, background electrolyte and copper ions were studied as well. The results showed that the pH, dosage of PAA and existence of copper ions affected the removal of nickel ions, while the background electrolyte had no effects. And the treated peat is an effective adsorbent for the removal of nickel ions in the concentrated solution.
