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.
