Abstract	This paper researched the adsorption properties of sodium polyacrylate(PAAS) to the copper(II) cation in wastewater, the adsorption effect of sodium polyacrylate were studied by the single factor such as adsorbent dosage, time, temperature and pH. The results show that: the absorbed ratio of the sodium polyacrylate was 97.14%, the adsorption capacity was 8.35 mg/g for the wastewater with the high content of copper(II) cation 200 mg/L, the reaction temperature was 50°C, the adsorbent dosage of the sodium polyacrylate were 30g/L, the time was 60 mins for adsorption, and the pH was 6 for the wastewater sample. The adsorption has Langmuir characteristics for the sodium polyacrylate adsorption of copper(II) cation. The adsorption mechanism was mainly monomolecular layer chemical adsorption, the temperature has little effect on adsorption capacity.
