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.
