Abstract: The use of ultrasound (US) at determination of chromium in kitchen salt using macrocomponent extraction was investigated. It has been found that US using let us to increase the degree of chromium extraction and improve , metrologic characteristics of the obtained results at kitchen salt analysis. It was shown that the use of double-frequent US allows us to increase solubility of sodium chloride in hydrogen peroxide from 42 up to 98 % and to increase the degree of chromium extraction from 94% up to 98% .dispersing and mixing effects are the determining factors of the US action on co-precipitation concentration. The method of atomic absorption determination of chromium in kitchen salt using macrocomponent extraction has been developed.
