Sensitivity and accuracy of atomic-absorption and atomic-emission with inductive connected plasma determination of the analytes in the salt samples, using ultrasound treatment, surface active substances (Triton Х100) and new standard composition samples, based on acetylacetonates of metals, was increased. An influence of Triton Х-100 concentration ant time of ultrasound treatment on the magnitude of analytical signal of the determined analytes was investigated. It was shown that maximal analytical signal occurs at ω of (Тriton Х-100) = 3% and ultrasound treatment during 20 minutes. Content of Zinc, Iron and Manganese was determined by two methods. An accuracy of the results of atomic-absorption measurements was checked by the “injected-found out” method. An absence of the systematic error was determined by variation of masses of the samples. The results, obtained by two methods, were compared. It was proved that run of the means is not sufficient and proved by random scatter. The limit of the analytes determination by atomic-absorption method is lower, than corresponding data from literature.
