| 摘 要： | 以含氟氯硫酸锌溶液为原料,采用离子交换法研究氟氯离子的脱除。试验筛选出D201树脂对氟氯离子有较好的吸附和解吸性能。多级动态试验结果表明,经D201树脂处理,将Cl-浓度由原液497.61mg/L降至58.77mg/L,Cl-脱除率88.19%;F-浓度由原液201.17 mg/L降至178.64mg/L,F-脱除率11.98%。动态吸附后的载氟氯D201树脂,用4mol/L硫酸液可将氟氯解吸,氟解吸率高于95%,氯解吸率高于99%。

| Abstract: | Removal of fluorine and chlorine ion by ion exchange was investigated applying zinc sulfate solution as raw material. D201 resin selected by experiments has good adsorption and desorption properties for fluorine and chlorine ion. The results of multistage dynamic test show that concentration of chlorine ion drops from 497.61 mg/L to 58.77 mg/L with removal rate of 88.19%, and concentration of fluorine ion drops from 201.17 mg/L to 178.64 mg/L with removal rate of 11.98%. D201 resin after dynamic adsorption was desorbed by 4 mol/L sulfuric acid solution, and desorption rate of fluorine and chlorine is 95% above and 99% above respectively. |
