The PASP (Polyaspartic Acid) was synthesized by using L-aspartic acid, and was charactered through IR. The optimal conditions by using the PASP to remove cadmium (II) in wastewater was determined. It was found that the maximum adsorbable capacity is of 1.97g/g and the removing rate is of 79.38% at the reaction temperature of 60°C, the time of 10 minutes for the constant temperature and the PH value of 6 for the water sample. Due to its many advantages of nontoxic, harmless, biological degradation and environment-friendly, the PASP is an ideal material in removing cadmium (II).
