Solvent extraction for the separation of zirconium and hafnium from strong nitric acid solution has been investigated by using several organophosphorous acids (D2EHPA, PC 88A and Cyanex 272) and its mixture. Among the single extractants, PC 88A showed the best performance for the extraction and sepa...
