Separation of scandium( III ) from iron( III ) and lutetium( III ) by bis(2,4,4-trimethylpentyl) phosphinic acid-N205-heptane emulsion liquid membrane
Fenxi Huaxue(1996)
Abstract
The separation of Sc( III ) from Fe( III ) and Lu( III ) by bis(2,4,4-trimethylpentyl) phosphinic acid-N205-heptane emulsion liquid membrane (ELM) was studied. The effects such as pH of the external aqueous phase, concentrations of Cyanex 272, N205 and the internal aqueous phase HCl on the transport of Sc( III ) were observed. Results show that it is possible to separate Sc( III ) from Fe( III ) and Lu( III ) with Cyanex 272-N205-heptane emulsion liquid membrane.
