Extraction of Sc (Ⅲ) by ELM Method Using PMBP as Caaarrier
Abstract:
Scandium (Ⅲ) was extracted by the emulsion liquid membrane (ELM) method using 4-benzoyl-3-methyl-1-phenyl-2-pyrazolin-5-on as a carrier.The extraction rate of Sc (Ⅲ) was more than 95.5% and the separation factor for Sc (Ⅲ) and mixed rare earths βSC/RE was 32.0.The optimum conditions for the extraction as follows:pH=1.7~3.8 for feed liquid,PMBP 0.4%,surfactant Span 80.3%,mixed solution of liquid paraffin and kerosene 5%,concentration of HCl in the internal phase 3mol/L,Roi=1:1,Rwe=20:1.
