Monitoring Copper in Fuel Ethanol by Anodic Stripping Voltammetry
Aug 06 2009 Comments 0
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.
