Abstract
The kinetics of Kjeldahl's digestion for nitrogen determination was compared between microwave and classical heating conditions. Various parameters (microwave power, concentrations, time)
of microwave digestion were studied in order to define the optimal digestion conditions. Finally, the Kjeldahl's analysis of nitrogen using microwave digestion was applied to various
pharmaceutical, agricultural and food products.
Key words: Microwave / Kjeldahl / nitrogen / digestion.
