Abstract

A mercury film electrode was used to determine Mg (II) in biodiesel by adsorptive stripping voltammetry in presence of sodium thiopentone. A linear response was obtained for Mg (II) in the concentration range of 6.0 x 10(-7) to 7.0 x 10(-6) mol L-1 for SWAdSV and 8.0 x 10(-7) to 9.0 x 10(-6) mol L-1 for DPAdSV with detection limits of the 2.9 x 10(-7) mol L-1 and 3.1 x 10(-7) mol L-1, respectively. The method was applied successfully to biodiesel samples and presented goods results of accuracy with recoveries close to 100.0 % for SWAdSV and DPAdSV. (AU)
