Abstract: The modern sample preparation by acidic decomposing of the sample using ultrasound treatment was done. An influence of Triton X-100 concentration on increasing the sensitivity of the atomic absorption determination of Copper and Iron was studied. It is shown that after the usage of Triton X-100 (? = 4%) the sensitivity of the atomic absorption determination of Copper increases by 1.5 times, and Iron does by 1.54 times. The content of Copper and Iron was determined by atomic absorption method in a oil sample using Copper and Iron acetylacetonates as standard samples of the composition. The correctness of the results of the analysis was checked by the "injected-found out" method. By varying the sample weight, the absence of substantial systematic error was confirmed. The detection limits of Copper is (Cmin=0,001 mkg/ml) and Iron is (Cmin=0,001 mkg/ml) that is lower that literature data.
Key words: Copper, Iron, sample preparation, ultrasound, Triton X-100, oil, atomic-absorption spectroscopy, acetylacetonates of Copper and Iron, metrologic characteristics.
