L'\u00e9chantillon est dig\u00e9r\u00e9 avec une solution d'acide chlorhydrique, de peroxyde d'hydrog\u00e8ne et d'acide nitrique. En milieu d'acide chlorhydrique dilu\u00e9, l'absorbance du fer est mesur\u00e9e par une flamme air-ac\u00e9tyl\u00e8ne \u00e0 la longueur d'onde de 248,3 nm \u00e0 l'aide d'un spectrom\u00e8tre d'absorption atomique.<\/p>\n
Cette m\u00e9thode est applicable au dosage du fer dans les alliages de zinc.<\/p>\n
