Abstract: An analisys of literature sources deals with determination of Cadmium in sunflower oil was done. It was shown that the best method to determine Cadmium in sunflower oil is atomic absorption spectrometry. Acidic extraction of Cadmium from oil was studied. It was established that mixture of Trilon B and nitric acid (1:1) is the best for the extraction. It let us to extract 81-90% of Cadmium per one time. After second extraction degree of it increase up to 92% and it is possible to enlarge it by boiling of the samples and mechanic mixturing with simultaneous shaking. It was established that using of ultrasound (US) to intensificate acidic extraction increase extraction degree up to 99%, and after the single extraction it is 96-97%. The optimal parameters of ultrasound are: frequency of 18-44 kHz, intensity 1,4-2,5 W/sm2,time-2-3 min. and ultrasound make an influence on the processes of Cadmium extraction. The methodic of atomic absorption determination of Cadmium in sunflower oil with detection limits of 0,005 mg/kg was developed.

Key words: atomic-absorption spectrometry, Cadmium, acidic extraction, sunflower oil,, ultrasound, metrologic characteristics.
