Abstract: The processes of reduction of various forms of mercury up to the atomic state have been studied. The use of ultrasound and the simultaneous action of ultrahigh-frequency and low-frequency ultrasound for the destruction of organic extracts of mercury have been investigated. The main factors of the action of ultrasound on the processes of reduction of mercury and on the processes of destruction of organic extracts of mercury have been experimentally proved, this are sound-chemical reactions with the participation of radicals. The advantage of the simultaneous action of ultrasound of different frequencies (high and low) relative to the degree of mercury extraction, which increases from 92.1 - 93.5 up to 96.1 - 98.5, has been experimentally shown. At the same time, the relative standard deviation increases significantly (Sr = 0.06 - 0.08).

Key words: mercury, cold vapor atomic absorption spectrometry, ultrasound, sample preparation, metrological characteristics.
