This European Standard specifies a method for the determination of mercury in aqua regia or nitric acid digests of sludge, treated biowaste and soil, obtained according to EN 16173 or EN 16174 using cold-vapour atomic fluorescence spectrometry (CV-AFS). The lower working range limit is 0,003 mg/kg (dry matter basis).
Schlamm, behandelter Bioabfall und Boden - Bestimmung von Quecksilber - Teil 2: Kaltdampf-Atomfluoreszenzspektrometrie (CV-AFS)
Diese Europäische Norm legt ein Verfahren zur Bestimmung von Quecksilber in Königswasser oder Salpetersäureaufschlusslösungen von Schlamm, behandeltem Bioabfall und Boden, hergestellt nach EN 16173 oder EN 16174, durch Kaltdampf Atomfluoreszenzspektrometrie (CV-AFS) fest. Die untere Bestimmungsgrenze liegt bei 0,003 mg/kg (Trockenmasse).
Boues, biodéchets traités et sols - Détermination du mercure - Partie 2: Spectrométrie de fluorescence atomique de vapeur froide (SFA-VP)
La présente Norme européenne spécifie une méthode de détermination du mercure soluble dans l'eau régale ou l'acide nitrique des boues, des bio-déchets traités et des sols, obtenus conformément à l’EN 16173 ou à l'EN 16174, par spectrométrie de fluorescence atomique en vapeur froide (SFA-VP). La limite inférieure de la gamme de travail est de 0,003 mg/kg (par rapport à la matière sèche).
Blato, obdelani biološki odpadki in tla - Določevanje živega srebra - 2. del: Metoda atomske fluorescenčne spektrometrije s tehniko hladnih par (CV-AFS)
Ta evropski standard določa metodo za določevanje živega srebra v zlatotopki ali izvlečku dušikove kisline blata, obdelanih bioloških odpadkov in tal, pridobljenega v skladu s standardom EN 16173 ali EN 16174, z uporabo metode atomske fluorescenčne spektrometrije s tehniko hladnih par (CV-AFS). Spodnja meja delovnega razpona je 0,003 mg/kg (suha osnova).

t H2O in 30 ml of hydrochloric acid (5.2), transfer to a 100 ml volumetric flask and fill to the mark with water. The blank concentration of mercury can be reduced by bubbling a stream of nitrogen through the solution for 30 min, if necessary. Prepare this solution on the day of use. A solution of lower concentration, e. g. 0,5 g in 100 ml, may be used with flow systems. Prepare this latter solution freshly on the day of use from the more concentrated solution by diluting with water. 5.8 Sodium borohydride solution, NaBH4, (NaBH4) = 30 g/l. 1 g sodium hydroxide, NaOH, is weighed into a 100 ml volumetric flask and dissolved in water. 3 g sodium borohydride, NaBH4, are weighed into a 100 ml volumetric flask, dissolved and diluted to the mark with the sodium hydroxide solution. 5.9 Mercury standard stock solution, 1 000 mg/l SIST EN 16175-2:2017
