Competitive bulk liquid membrane transport of Co(II), Ni(II), Zn(II), Cd(II), Ag(I), Cu(II) and Mn(II), cations using 2,2′-dithio(bis)benzothiazole as carrier
چکیده انگلیسی

A series of competitive metal-ion transport experiments has been performed. Each involved transport from an aqueous source phase across an organic membrane phase into an aqueous receiving phase. The source phase contained equimolar concentration of Co(II), Ni(II), Zn(II), Cd(II), Ag(I), Cu(II) and Mn(II) metal cations. The transport experiments of metal cations were carried out by 2,2′-dithio(bis)benzothiazole (DTB) in chloroform (CHCl3). The source phase being buffered at range pH of 4–6.5 and receiving phase being buffered at pH 3. The obtained results show that the selectivity and the efficiency of Ag(I) transport from aqueous solutions are observed in this investigation. The effect of concentration of palmitic acid in the transport efficiency of Ag(I) ion was also conformed.
