摘　　要：研究了用Ce_2(CO_3)_3作除氟剂从锌电解液中脱除氟离子。通过正交试验和单因素试验,考察了Ce_2(CO_3)_3用量、反应时间、反应温度、反应终点pH对除氟效果的影响。试验结果表明:各因素对除氟效果的影响顺序为除氟剂用量>反应温度>反应终点pH>反应时间;在除氟剂用量1.0g(50.7g除氟剂/g F-)、反应温度50℃、反应终点pH=5.0、反应时间90min条件下,氟去除率达93.98%,除氟效果较好。Ce2 （CO3）3 was used as fluorine-removal agent to remove fluorine in the zinc electrolyte. The effects of fluorine-removal agent usage, reaction time, temperature and reaction endpoint pH on defluoridation were researched by the combination of orthogonal and single-factor experiments. The results show that the influencing order on defluorination effect is fluorine-removal agent usage temperature〉reaction endpoint pH〉reaction time. The defluoridation rate is 93. 98% under the conditions of fluorine-removal agent usage of 1.0 g, temperature of 50 ℃, endpoint pH of 5.0 and reaction time of 90 min. The fluorine-removal effect is good.
