Abstract
Synergic extraction of different essential and toxic metal ions such as Mn(II), Co(II), Zn(II), Hg(II), Cd(II) and Se(IV) has been carried out using toluene-3,4-dithiol (TDT) and trioctylamine (TOA) in chloroform. A strong synergic effect in the extraction of Co(II), Mn(II) and Zn(II) has been observed. The effect of different anions on the extraction has also been analyzed. Ascorbate ions can easily separate Hg(II) and Se(IV) ions. The stability of synergic adduct and reaction mechanism are discussed.
