Summary

Wet decomposition of olive leaves in open and closed systems, low temperature ashing, UV-irradiation and combinations of these methods have been tested for their application in the determination of heavy metals by anodic stripping voltammetry. Completeness of the decompositon and interferences in the electrochemical determination have been evaluated. Wet decomposition with perchloric acid, low temperature ashing and a combination of pressurized digestion and UV-irradiation were found to be suitable for application in electrochemical measurements. The most serious interferences were observed with well but not fully decomposed samples, such as those obtained by wet decomposition with nitric acid in an open system.
