|Abstract:||Fe (III) separated quantitatively from its binary mixtures with Cr(III), Mn(II), Co(II), Ni(II), Zn(II), Hg (III), Mg(II) and from steel samples using a synergic combination of 4-phenyl-2,4-butanedione(HA) with triphenylphosphine oxide(Ph3PO). However, copper (II) and silve (I) interfere. The extraction and stability constants of the synergic species Fe(NCS)A2Ph3Po) are found to be:1.2 109 and 7.3 104 respectively.|
