Abstract: The use of ultrahigh frequency ultrasound for the intensification of the acid extraction of lead and cadmium from fats and oils is proposed. The optimal parameters of ultrasound were experimentally established: frequency 12-15 MHz, intensity 5.0-7.0 W/cm2 for 5-8 minutes. The intensifying effect of microwave ultrasound is based on a combination of acoustic flows and cavitation effects. It has been shown that the use of intensification of acid extraction by microwave ultrasound makes it possible to increase the degree of extraction of lead and cadmium to 98-99%, which is more effective than the use of low-frequency ultrasound - 92-93%, and even the use of simultaneous exposure to high and low frequency ultrasound - 96 - 97%.

Key words: fats and oils, high frequency ultrasound, recovery, lead and cadmium.
