| Abstract: |
| Industrial experiment on removal of fluorine and chlorine ion from zinc sulfate solution by ion exchange was carried out. Effects of adsorption time, desorption time, and desorption resin pH value on removal of fluorine and chlorine from zinc sulfate solution were studied. The experimental results show that under the optimum process parameters, fluorine and chlorine removing rates is 61.47% and 93.59% respectively during adsorption process. In desorption process, fluorine and chlorine desorption rate is 94.11% and 97.50% respectively. In regeneration process, fluorine and chlorine volatilization rate is 92.66% and 98.66% respectively. The solution in whole process is recycled and waste water discharge is reduced. |
