摘要:
研究了有机溶剂萃取净化湿法磷酸时,杂质离子浓度对磷酸萃取相平衡的影响.结果表明:磷酸的萃取率随初始水相中钙离子、镁离子、硫酸根离子、氯化钠浓度的增大而逐步增大,随铁离子浓度增大而减小.水相中有机物浓度随钙镁离子浓度的增大而降低,随铁离子、硫酸根离子浓度增大呈先增大后减小的变化趋势.
Abstract:
By organic solvent extraction to purify phosphoric acid, this article focuses on the impurity ion concentration on the phosphate extraction equilibrium were studied. The authors found that the extraction rate of phosphate with the initial water phase of calcium, magnesium, sulfate, sodium chloride concentration increases, gradually increase with increasing iron concentration showed decreasing trends,water phase organic compounds with calcium and magnesium concentration with the increase of decrease, with the iron ion, sulfate ion concentration increases at first and then decreased the trend.
