摘要：
A comprehensive technique for determining Ni and V in crude oils in a wide range of their concentrations is described. The procedure involves ETAAS, ICP-AES, and autoclave sample preparation. The optimal conditions for the mineralization of oil samples in Ankon-AT2 analytical autoclaves in a mixture of HNO3 and H2O2 are found. Oil and condensates of oil- and gas-bearing basins are taken as objects of investigation. The concentrations of Ni and V in these systems are estimated and the regularities in the distributions of Ni and V are revealed.
