A mercury film electrode was used to determine direct and simultaneously Pb(II) (at −410mV) and Cu(II) (at −100mV) in biodiesel by anodic stripping voltammetry. A linear response was obtained for Pb(II) and Cu(II) in the 2.00×10−8–1.00×10−7molL−1 concentration range and detection limits were 2.91×10−9molL−1 and 4.69×10−9molL−1 for Pb(II) and Cu(II), respectively, with recovery around of 100.0%.
