dc.description.abstract The simple and fast method for analysis of Propyl gallate (PG) in biofuels was proposed in this paper. Voltammograms of antioxidant under study were recorded using linear sweep voltammetry method at a gold disc electrode in supporting electrolyte containing 0.18 mol L-1 H2SO4 and 10 % ethanol. For purposes to monitor effects on fuel quality caused by oxidative degradation, the proposed method was applied to samples of biodiesel and Ekodiesel® (the blend of biodiesel with fuel diesel). The analysis of PG can be performed without pretreatment of Ekodiesel samples, and after extraction using distilled water in case of biodiesel samples. eng

dc.description.abstract-translated Byla navržena jednoduchá a rychlá metoda pro stanovení antioxidantu v biopalivech. Voltametrický pík studovaného antioxidantu byl zaznamenán metodou lineární voltametrie (LSV - linear sweep voltammetry) na zlaté diskové elektrodě v základním elektrolytu obsahujícím 0,18 mol.l-1 H2SO4 a 10% ethanol. Z důvodu sledování vlivu kvality biopaliv na jejich oxidační degradaci byla navržená metoda aplikována na vzorky bionafty a směsné motorové nafty. cze
