Rezumat: Heavy oil and heavy oil residues often contain a wide range of non-ferrous, rare and noble metals in high concentration. Standard methods of elemental analysis of heavy oil and heavy oil residues does not exist. Two approaches for the oil metalliferous feedstock analysis were proposed. There are direct analysis by ICP-AES and preliminary extraction of metals to the aqueous solution of an inorganic acid, followed by instrumental analysis. The possibility of pre-concentration of metals oil prior to analysis was shown. The developed methods of analysis allows identifying most of the elements in the heavy oil feedstock for a short time with a high degree of reliability.
