Our goal was to work out a procedure aimed at determining low concentrations of toxic elements in oil products using atomic-emission spectrometry to assess products safety.

We performed a comparative examination of various mineralization techniques, studied extraction conditions impacts, as well as autoclave and microwave mineralization impacts on the results of toxic elements determination in oil raw materials and oil products. We detected that complete mineralization enabled achieving the least results inaccuracy in comparison with acid extraction.

We developed parameters for atomic-emission analysis of determining Fe, Cu, Ni, Pb, and Cd, in oil raw materials and oil products. We defined a wave length for each element and background correction; we also determined a device parameters (generator power, sample feeding speed, spraying speed), chose a cleft width and an analysis regime for data calculation.

Basing on the conducted research we created a high-precision procedure for determining low concentrations of such toxic elements, as Pb, Cd, As, Hg, Cu, Fe, and Ni, with atomic-emission spectrometry technique. Standard deviation in the procedure repeatability amounts to 1.4–4.3 %. Standard deviation in the procedure reproducibility amounts to 10.1–11.8 %. maximum expanded uncertainty in measuring concentrations of Cd, Pb, and As, amounts to 30.6 %; Hg, 23 %; Cu, Fe, ands Ni, 21 %; Pb, 33 %.

Application of the created procedure will help to enhance control over quality and safety of food products and to lower alimentary morbidity.
