Microwave-assisted digestion and mineralization in open system were compared by applying these procedures for preparing 23 laboratory-made and 3 samples of commercial chocolate. After samples digestion, the content of Zn, Cd, Pb and Cu was determined by potentiometric stripping analysis. The process of mineralization showed better reproducibility; however, based on numerous advantages, priority should be given to microwave digestion. The most pronounced drawback of microwave-assisted digestion is the affinity of feflon to incorporate sample components at elevated temperatures and to provoke sample contamination.
