| Abstract: | The special polymeric adsorbents were used to treat the wastewater produced from manufacturing accelerant CA. Effects of pH values, temperature and current velocity of wastewater on the adsorption of resins were studied. The desorption efficiency for H 2SO 4 was investigated. The results showed that this method is suitable for removal of COD Cr and the resin has a good adsorption and desorption performance. About 98% COD Cr removal was obtained under the optimum adsorption conditions. The concentration of COD Cr has been reduced from 20 000 mg/L to less than 300 mg/L. |
