Abstract

A new micelle-mediated extraction method for ultra-trace quantities of V(V) and Pb(II) as a prior step to their simultaneous spectrophotometric determination has been developed. Alizarin red S (ARS), was used as chelating agent in presence of Tween-80 miceller media at pH 5.5, respectively. Mean centering (MC) of ratio spectra has been used for the simultaneous analysis of these metal ions. The analytical characteristics of the method such as (Beer’s law, detection limit and relative standard error (R.S.E.) were calculated. Linearity was obeyed in the concentration range 0.255-4.58µg/ml of V(V) and 0.345-6.14 µg/ml of Pb(II). The detection limit of the method is 0.60 and 0.51 µg/ml for V(V) and Pb(II) respectively. The interference effect of some anions and cations were also tested. The method was applied to the simultaneous determination V(V) and Pb(II) in water samples and alloys.
