Electrothermal atomic-absorption determination of vanadium

Abstract:
Factors such as sample nature, matrix and heating programme have been found to influence both the sensitivity and precision of the determination of vanadium by electrothermal AAS. The reciprocal sensitivity, detection limit and precision (RSD) are 55 pg, 86 pg and 4%, respectively for aqueous solutions and 88 pg, 80 pg and 4% for organic solutions. Only tungsten and nitric acid have been found to interfere appreciably. Moderately concentrated sodium chloride solutions (6%) can be analysed for vanadium (0.05 mug/ml) without background correction, as can the acid digests of phosphate rocks and crude petroleum samples.
