CEN/TS 17701-3:2022

Plant biostimulants - Determination of specific elements - Part 3: Determination of mercury

This document specifies a method for determination of the content of mercury (Hg) in plant biostimulants using (cold) vapour generation apparatus coupled to an atomic absorption spectrophotometer and a method using a direct amalgamation technique. It is applicable to aqua regia digests prepared according to CEN/TS 17701-1.
NOTE    It is also possible to use other suitable methods for the determination of mercury described in Annex A if users prove that the method gives the same results as the methods described in this document.
This document is also applicable to the blends of fertilizing products where plant biostimulants are the main part of the blend. Otherwise, the Technical Specification for the main part of the blend applies.

Pflanzen-Biostimulanzien - Bestimmung spezifischer Elemente - Teil 3: Bestimmung von Quecksilber

Dieses Dokument legt ein Verfahren zur Bestimmung des Quecksilbergehalts (Hg) in Pflanzen-Biostimulanzien mittels eines Systems der (Kalt )Verdampfungstechnik, gekoppelt mit einem Atomabsorptionsspektrometer und einem Verfahren, das auf einer direkten Amalgamierungstechnik beruht, fest. Es ist für Königswasseraufschlüsse anwendbar, die nach CEN/TS 17701 1 hergestellt werden.
ANMERKUNG   Auch die Anwendung anderer, in Anhang A beschriebener, geeigneter Verfahren der Quecksilber-bestimmung ist möglich, sofern die Anwender nachweisen, dass das Verfahren zu gleichen Ergebnissen führt wie die in diesem Dokument beschriebenen Verfahren.
Dieses Dokument ist auch für die Mischungen von Düngeprodukten anwendbar, in denen die Pflanzen-Biostimulanzien der Hauptbestandteil der Mischung sind. Andernfalls gilt die Technische Spezifikation für den Hauptbestandteil der Mischung.

Biostimulants des végétaux - Dosage des éléments spécifiques - Partie 3 : Dosage du mercure

Le présent document spécifie une méthode pour la détermination de la teneur en mercure (Hg) dans les biostimulants des végétaux avec un appareil de génération de vapeur (à froid) couplé à un spectrophotomètre d’absorption atomique et une méthode utilisant une technique d’amalgamation directe. Il est applicable aux digestats à l’eau régale préparés conformément à la CEN/TS 17701-1.
NOTE Il est aussi possible d’utiliser d’autres méthodes adaptées pour le dosage du mercure décrites dans l’Annexe A, si l’utilisateur prouve que la méthode conduit aux mêmes résultats que les méthodes décrites dans le présent document.
Le présent document est également applicable aux mélanges de fertilisants dont la majeure partie est constituée de biostimulants des végétaux. Dans le cas contraire, la Spécification technique relative au constituant principal du mélange s’applique.

Rastlinski biostimulanti - Določevanje specifičnih elementov - 3. del: Določevanje živega srebra

Ta dokument določa metodo za določevanje vsebnosti živega srebra (Hg) v rastlinskih biostimulantih z uporabo naprave za ustvarjanje (hladne) pare, povezane z atomskim absorpcijskim spektrofotometrom, in metodo, ki uporablja tehniko neposredne amalgamacije. Uporablja se za izlužke zlatotopke, pripravljene v skladu s standardom CEN/TS 17701-1.
OPOMBA:    Možna je tudi uporaba drugih ustreznih metod za določanje živega srebra, opisanih v dodatku A, če uporabniki dokažejo, da izbrana metoda zagotavlja enake rezultate kot metode, opisane v tem dokumentu.
Dokument je uporaben tudi za mešanice sredstev za gnojenje, pri katerih so rastlinski biostimulanti glavni del mešanice. V nasprotnem primeru se uporablja tehnična specifikacija za glavni del mešanice.
