Abstract
Based on the analysis of the structure property of the ions in the cuprous chloride wastewater, the study on the ion exchange of the cuprous chloride wastewater and the regeneration of resin had been experimentally investigated with 201×7OH— strong-alkali negative ion resin and 732Na strong-acidity positive ion resins. The influence on the disposal effect from the variation of pH and the addition of NaCl and Na2SO4 had been examined. The results showed that for the negative ion exchange reaction. If pH was adjusted with HCl, the concentration of copper in the waste water decreased slowly as pH decreases. If pH was adjusted with H2SO4, the concentration of copper in the waste water increased slowly as pH decreases. The addition of NaCl and Na2SO4 could enhance the exchange efficiency of negative ion. For the positive ion exchange reaction, the exchange efficiency of positive ion could be enhanced by the addition of HCl or H2SO4 which decreases pH; the addition of NaCl and Na2SO4 could enhance the exchange efficiency of positive ion, but was not significant.
