Abstract: In the work a promising method of sample preparation was used - emulsification of the oil sample with subsequent ultrasound treatment. The optimal conditions for the analysis were selected. It was found that the best extraction of Manganese and Iron was observed in emulsions of Triton X-100 aqueous solution with 5% mass concentration and 20 min. of ultrasound treatment. It was proved that using of the Triton X-100 modifier and the ultrasound treatment of emulsions increases the sensitivity of the detection of Manganese and Iron by 1.5 times. For calibration of measurements for the first time new standard composition samples based on acetylacetonates of Manganese and Iron were used. The variation of the sample weight was shown that the technique does not contain a significant systematic error. The validity of the results has been checked using the "injected-found out" method. The results of two independent methods were compared according to F- and t-criteria. The obtained results were equivalent, the difference between them was not significant and was justified by a random distribution. The detection limits of Iron and Manganese were estimated, which were 0.002 and 0.001 mg/l, respectively.
