摘要

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