Monitoring Copper in Fuel Ethanol by Anodic Stripping Voltammetry
Aug 06 2009 Read 1841 Times
The presence of copper in fuel ethanol blends negatively affects engine performance. Thus, the US ASTM D 4806 and the European EN 15376 both restrict the amount of copper in fuel ethanol to 10 µg/L. Anodic stripping voltammetry (ASV) is the determination method of choice, as it allows the quantification of Cu(II) without any sample pretreatment.
