摘要：

Vanadium determination was carried out in petroleum samples by Atomic Absorption Spectrometry with Electrothermal Atomization. Three procedures of sample preparation were studied: xylene solution, dry calcination and wet digestion with sulphuric acid and hydrogen peroxide. The xylene dissolution and dry calcination were the optimum procedures.
