Co-extraction and separation of zirconium and hafnium by long-chain amines from sulphate media

Co-extraction and separation of zirconium and hafnium by long-chain amines from sulphate media

Talanta 25(9): 523-525

The extraction of Zr and Hf from sulphuric acid systems by solutions of Primene JMT (a long-chain primary amine) in kerosene, is described. The effect of contact time, free acidity, solvent concentration and temperature, has been thoroughly examined. A rapid improved method for HfZr separation is suggested.
