摘要:
采用732强酸性阳离子交换树脂对湿法磷酸中金属杂质的脱除进行了研究.考察了搅拌速度、温度、树脂用量、时间因素对金属杂质去除率的影响.结果表明：在搅拌速度为400 r/min，温度为30 ℃，树脂和湿法磷酸的质量比为9∶10，时间为5 min的条件下，效果最好.其中铁的去除率达到66.21%，铝的去除率达到85.87%，镁的去除率达到89.76%，钙的去除率达到93.29%.
Abstract:
he removal rate of metal impurities in WetProcess Phosphoric Acid with 732 strongacid cation exchange resin was researched. Some important factors which affect the removal rate of metal impurities such as the stirring speed， the temperature， the mass ratio of duolite to Phosphoric Acid， the reaction time were studied respectively. The results show that the removal efficiency of iron， aluminum， magnesium， calcium can be up to 66.21%，85.87%，89.76%，93.29%，respectively, when the stirring speed was 400 r/min，the temperature was 30 ℃，the mass ratio of doulite to Phosphoric Acid was 9∶10，the reaction time was 5 min.
