The polyacrylonitrile grafted starch was obtained from the acrylonitrile monomer with sago starch and grafting reaction was carried out by free radical initiating process. The purpose of this research was to study of poly( amidoxime) resin used for recovery metal ions and rate of metal ions study. For metal ions sorption capacity, it was measured by the batch equilibration with varying pH solutions (PH 3-6). It was found that metal ions uptake by resin was increased with increasing pH up to 6. The sorption capacity of Zn²� and Cd²� metal ions by resin were pH dependent. The sorption capacities for zinc metal ions are higher than cadmium metal ions sorption capacities. The resin selectivity toward both these metal ions is Zn²> Cd²�. From the kinetic exchange for zinc metal ion, it was found that the rate of sorption capacity for zinc metal ion is rapid at t½<10.
