Resumo

A boron-doped diamond electrode was used at the interface of biodiesel and water in conjunction with square-wave voltammetry to promote the detection of a model molecule (ferrocene). The addition of LiClO(4) to the oil phase increased the detection of ferrocene five-fold as compared with an unsupported oil phase. A cathodic surface pretreatment of the BDD electrode caused no oscillation of currents and promoted a high stability within the system. Our successful use of this system suggests the possibility for its application in the analysis of other contaminants within biodiesel including liposoluble pesticides and glycerol. (AU)
