Abstract: Coprecipitation of lead,copper and cadmium on magnesium hydroxide was studied. Coprecipitation mechanism was proposed. The use of two-frequency ultrasound for intensification of coprecipitation was investigated. It has been found that dispersing and mixing effects are the determining factors of the US action on co-precipitation concentration. The method of determination of lead, copper and cadmium in natural brines, using coprecipitation and ultrasound intensification has been developed. The content of lead, copper and cadmium in the natural brines of Ukraine was determined. It was shown that the use of double-frequent US allows us to increase the degree of determination lead, copper and cadmium from 92-95% up to 97-98% and also to improve metrological characteristics to determine analytes in natural brines.

Key words: atomic absorption spectrometery, natural brines, ultrasound, coprecipitation, metrologic characteristics.
