The removal of nickel via Polyacrylic acid sodium salt was investigated in Polymer-Enhanced Ultrafiltration. Solution pH and nickel removal have a direct correlation. The optimal loading ratio was found to be between 3 and 4 g PAANa/g nickel. Solution pH had no effect on membrane fouling. Loading ratios had no effect on membrane fouling and it was discovered that 30,000 kDa PAANa causes large decreases in membrane permeability. The complexation of PAANa and nickel was characterized by binding capacity, the complexation equilibrium constant, and nickel denticity.
