Abstract: The extraction of all rare earth elements(except Pm)from thiocyanatc solution with mixtures of phenanthroline(Phcn)and hydroxy-isobutyric acid(HHIBA),salicyl acid(Hsal)in chloroform has been investigated.The results of experiments show that there is obvious 'synergic effects' either in the system of-RE(w)3+HHlIBA(0)-Phen(0)-SCN-(w)or in the system of RE(w)3+-Hsal(0)-Phen(0)SCN(w)and there exists obvious 'tetrad effects' in the two synergic system.
