Abstract
The effect of metallic traces present in crude oils has raised a major concern to develop aquantitative analytical method. A Wet-Ashing procedure has been used for sample pretreatment to determine Al, Cd, Fe, K, Li, Mn, Ni, Pb, Sn and V in five (5) Saudi Arabian crude oil samples as multi-elements by Sciex elan ICP/MS. The relative standard deviation was found not more than 3% for five replicate samples.
