Abstract: The paper embodies details on the extraction of different 3d transition metal ions namely Ti(IV), V(IV), Cr(III), Fe(III), Mn(II), Co(II), Ni(II), Cu(II) and Zn(II) in a toluene solution of Cyanex 923 from different mineral acid media. Effect of some important parameters such as the concentration of extractant and metal ion and nature of the diluent on the partition of Ti(IV), V(IV), Fe(III), Cu(II) and Zn(II) is examined. The extracting species of these metal ions are proposed and the loading capacity of Cyanex 923 is checked. The hydrolytic stability of the extractant solution has been examined and a procedure developed for its recycling. The extraction behavior of a number of commonly associated elements like Ce(IV), Al(III), Ga(III), Mg(II), Cd(II) and Pb(II) encountered in some of the matrices has also been investigated. Based on the distribution data it has been possible to achieve various binary separations of analytical interest involving 3d transition metal ions.
