用溶剂萃取法从废酸液中分离钪、钛
Separation of Scandium,Titanium From Waste Acidic Solution by Solvent Extraction
摘要
Abstract
Separating scandium and titanium from waste acidic solution by solvent extraction was researched .The results show that using one component system of P204 + kerosene ,the extraction of scandium is lower .The extraction of scandium is increased significantly after adding TBP to the extractant ,but third phase is still there .The organic phase is added acetophenone of 3% - 5% ,the three‐component system can effectively solve the problem of third phase ,and water phase and organic phase speed up separating ,the interface is clear .The optimal process conditions for separating scandium and titanium are that V a /V o = 5/1 ,2 step countercurrent extraction ,extraction time is 10 min ,extraction agent is 12% P204 + 5% TBP + 3% acetophenone + 80% kerosene .Under the optimal process conditions ,the average extraction rate of scandium is 91 .7% ,and the average extraction rate of titanium is 0 .69% .The separation effect of scandium and titanium is good .关键词
