Abstract: A systematic study of the effect of microwave, ultrasound and acid decomposition of hair samples on the results of atomic absorption and atomic emission with inductively coupled plasma determination of Lead and Cadmium was held. The data were systematized, comparative tables were compiled, the optimal method for sample preparation of hair samples was chosen - an ultrasonic treatment method. To increase the sensitivity of modern methods for the determination of analytes in the analyzed samples, it was proposed to use Triton X-100 (w = 4%). The results obtained by two independent methods were compared using the F- and t-criteria. It was shown that the difference in the deviations of the results is insignificant and can be explained by random variation. The accuracy of the atomic absorption determination of analytes in the samples was verified using the “injected-found” method.
