| Summary: | Amethod for the determination of traces of arsenic in food has been developed
based on electrolytic arsine generation and atomic absorption spectroscopy
detection. The essence of the method is the addition of copper and tin salts
to the electrolyte solution, enabling a fast and effective arsine evolution.
The advantage of this method lies in the fact that it enables the
simultaneous concentration of heavymetals, such as cadmium and lead, on
cathode. The applicability of themethod was illustrated by determining the
arsenic content in some food samples based on vegetable oils and by
comparing the results with those obtained by the classical technique of
chemical hydriding with sodium tetrahydroborate. |
