氯化铝中萃取铁工艺
Extraction of Fe(Ⅲ) from Aluminum Chloride
摘要
Abstract
The extraction behaviors of Fe (Ⅲ) in the preparation of high purity aluminum chloride with N,N, N′, N′-tetrabutyl malonamide ( TBMA ) , N, N, N′, N′-tetraoctyl-3-oxy-glutaramide ( TODGA ) and methyl isobutyl ketone( MIBK) have been investigated .The results show that the extraction efficiency of Fe (Ⅲ) with TBMA or MIBK is 90％ when the concentration of hydrochloric acid in the aluminum chloride solution is 4 mol/L.TODGA shows an excellent separation performance .When the concentrations of Al 3+, Fe3+, and HCl are 2.0 mol/L, 0.0036 mol/L(0.2 g/L), and 1.2 mol/L, respectively, in the solution of aluminum chloride , the extraction efficiency of Fe 3+is more than 99.9％ with 0.20 mol/L TODGA in cyclohexane or n-dodecane .After several extractions , the iron impurities in the aluminum chloride can be deeply removed and the iron content in the solution is lower than 0.01 mg/L, indicating that it has potential application in industrial production .关键词
