Determinación de mercurio en vinos por espectrofotometría de absorción atómica sin llama

Abstract

[ES] Se describe un método de determinación de Hg. en vinos por E.A.A. sin llama, previa oxidación de la materia orgánica según tres procedimientos distintos: 1º. Con permanganato potásico en ácido sulfúrico. 2º. Con ácido crómico al 5% en ácido sulfúrico. 3º. Con ácido nítrico 100% y ácido crómico al 5% en ácido sulfúrico. El ión Hg++ liberado es en los tres casos reducido posteriormente a su forma metálica por acción del Sn++ y arrastrado por corriente de aire hasta la célula del espectrofotómetro en un sistema cerrado cuyo esquema se representa. Se comparan los resultados obtenidos con cada uno de los procedimientos de oxidación: el tercer porcedimiento presenta ventajas de sensibilidad, reproductibilidad y rapidez.

[EN] Here we described a method for the determination of Hg in wine by E.A.A. without flame, with a previous oxidation of the organic matter, according to three different procedures. 1st. With Potassium Permanganate in Surfuric Acid. 2dr. With Chromic Acid at 5% in Sulfuric Acid. 3rd. With Nitric Acid 100% and Chromic al 5% in Sulfuric Acid. The ion Hg++ is in the three reduced subsequently to the metallic structure by the action of Sn++ and dragged along by a draft to the cell of the Spectrophotomete rin a close system, the scheme of which is represented. The obtained results are compared with each one of the oxidation procedures: the 3rd. procedure shows some advantage of sensitivity, reproductivity and rapidity.
