Peculiarities of nickel determination by the method of atomic absorption spectrometry with electrothermic atomization
Abstract
Nickel is a biogenic, conditionally essential element that is present in all foods in low concentrations. The daily requirement for nickel is 35-60 μg. Excessive consumption of nickel leads to negative health consequences. Control of the content of nickel in food products is carried out by photometric, gravimetric and atomic absorption methods. A method for the determination of nickel in food products based on atomic absorption spectrometry with electrothermal atomization is presented in the article. The temperature-time program of the graphite atomizer for the determination of nickel has been optimized. The correctness of the results obtained is confirmed by the example of a standard sample of lobster composition.
