I. Yurchenko, O. S. Kalinenko, A. N. Baklanov, E. A. Belova, L. V. Baklanova // Internetional scientific journal Theoretical & Applied Science. Section 9 Chemistry and chemical technology. – 2016. – Vol. 33, № 1. – P. 158–163.https://repo.knmu.edu.ua/handle/123456789/12663The use of the simultaneous action of two ultrasonic frequencies and pulsed ultrasound in the analysis of sugar-based products for lead, copper and cadmium have been studied. It is shown that the use of two-frequency ultrasound improves the metrological performance analysis as compared to use only a single ultrasonic frequency. The technique of atomic absorption determination of lead, copper and cadmium with sensitivity 0,067, 0,013 i 0,004 mg / kg respectively have been proposed.ensugardual-frequency ultrasoundthe metrological characteristicsArticle
