USE OF MICROWAVES FOR DECOMPOSITION FOOD PRODUCTS IN THE DETERMINATION HEAVY METALS BY ATOMIC ABSORPTION

RGTBTL

Abstract

On the example of the study of milk, meat, eggs and sunflower oil for the content of toxic elements cadmium, lead, copper, zinc, iron, tin, using microwave radiation in the process of preparing samples for analysis by atomic absorption. The method of mineralization using microwave exposure was compared with the standard method of wet salinization. It is shown that the time of complete salinization in the case of the use of microwave radiation is reduced by an average of 5 times compared to the standard method. At the same time, the depth of salting corresponds to the standard method. In addition, it became possible to reduce the weight of the analyzed sample by 15-25 times. Thus, a comprehensive assessment of the possibility and effectiveness of the use of microwave radiation in the mineralization of images of milk, meat, eggs, sunflower oil shows its prospects and effectiveness.
