摘要:
研究了5种低水溶性萃取剂(异戊醇、正己醇、异丙醚、TBP和MIBK）对湿法磷酸的萃取效果和对阴阳离子的脱除效果，确定选用TBP与MIBK的复合萃取体系.通过实验得出该萃取体系对湿法磷酸的净化工艺条件为相比41，萃取温度60 ℃，搅拌速度300 r/min，搅拌时间15 min，在该工艺条件下净化的磷酸满足工业磷酸的要求.
Abstract:
It were researched extraction efficiency of the wetprocess phosphoric acid (WPA),and selectivities of the iron ion and the sulfate ion of five kinds of low watersoluble extractant(isoamyl alcohol,hexanol,isopropyl ether,TBP and MIBK).It were determined to select TBP and MIBK for the Complex extraction system.By experiments,it were determined WPA purification processing conditions that was phase ratio 41,extraction temperature 60 ℃,stirring speed 300 r/min and mixing time 15 minutes for the extraction system.Under the conditions,the products which were extracted from WPA meet the quality requirements of Phosphoric acid purification.
