Abstract
The combined method volatile phase-atomic spectroscopy is an improvement in comparison with the conventional method of liquid sample introduction. The generation of a volatile phase by sublimation from an ethanolic solution of zinc acetylacetonate monohydrate and the obtainment of an analytical signal by AAS is proposed in this paper. The volatile phase is introduced in a silica tube by means of a nitrogen stream as carrier gas. The proposed method gives an improved sensitivity of 6.2 times with respect to the introduction of the same sample in liquid phase and more than 30 times with respect to the introduction of the zinc as chloride in aqueous solution.
