磷酸萃取伴生结晶的热力学研究

The Thermodynamic Study on Phosphate Extraction Accompanying Crystallization

摘要: 本文对磷酸在TBP中萃取伴生结晶过程的研究，对该过程有了初步了解和认识。研究了磷酸在TBP中的溶解度、介稳区宽度及降温速率和磷酸浓度变化对该过程的影响及变化行为。结果表明，随着降温速率的增加，介稳区宽度相应增大，这个变化和磷酸在水溶液中介稳区宽度变化类似。

Abstract: The research for associated Tri-Butyl-Phosphate (TBP) extraction phosphoric acid crystallization process is carried out. And the results can make the process clearly. The solubility of phosphoric acid in TBP, Metastable Zone Width (MZW) and cooling rate and concentration of phosphoric acid are investigated for the influence and behavior of this process. The results show that the MZW data increases with the increasing cooling rate. It shows the similar behavioral changes with phosphoric acid in water.
