Abstract
This article describes the determination of Eu by adsorptive cathodic stripping voltammetry after complexation with N-nitroso-N-phenylhydrox ylamine (cupferron). The accumulation of the complex at the HMDE was p erformed at 0.0 V and the subsequent potential scan was made in the sq uare wave mode. The analyte signal occurred at -0.88 V. The detection Limit is 0.06 nmol dm(-3). The effect of instrumental and chemical par ameters on the peak height and potential was investigated. The same te chnique can be used for the determination of ytterbium and of the othe r rare earth elements (REEs) after separation.
