Abstract
The disposition of petroleum was managed to sulphuric ash used of sulphuric acid and to watery solution, Zinc, Lead and Copper contents contained in it were analysed by the apparatus of Anodic Stripping Voltammetry (ASV) used of mercury electrode.
The number of analytical sample was crude oil 44 samples, Heavy oil 9 samples and marine weathering oil 15 samples.
We conclude from the analysis of them described above that: -
(1) in crude oils, content of Zinc include 0-16 ppm, Lead is 0-5 ppm, Copper is 0-3 ppm, but we could not recognize the result being characterized by the place of origin.
(2) in heavy oils, there is not little relation between the property to metal contents.
(3) in marine weathering oils, metal contents have a tendency to be enriched respectively.
However, we conclude that analysis of metal contents in petroleum is exceedingly available, with the object of discrimination about identity of oil samples.
