Fertilizers - Determination of chelating agents in fertilizers by chromatography - Part 1: Determination of EDTA, HEEDTA and DTPA by ion chromatography
N EN 13368-1
Annotation
This European Standard specifies a method for the chromatographic determination of the total amount of each of the individual chelating agents EDTA, HEEDTA, and DTPA in fertilizers containing one or more of these substances. The method allows the identification and the determination of the total water soluble fraction of each of these chelating agents. It does not allow to distinguish between the free form and the metal bound form of the chelating agents.
NOTE EDTA, HEEDTA and DTPA are abbreviations used in this European Standard for the sake of simplicity. For complete names see Annex A.
This method applies to fertilizers containing chelates of one or more of the following micro-nutrients: cobalt, copper, iron, manganese, zinc and with a mass fraction of at least 0,1 %.

Удобрения - Определение chelating агентов в удобрениях хроматографией - Часть 1: Определение EDTA, HEEDTA и DTPA хроматографией иона
Этот европейский стандарт определяет метод для хроматографического определения общей суммы каждого из отдельных chelating агентов EDTA, HEEDTA и DTPA в удобрениях, содержащих один или больше этих веществ. Метод позволяет идентификацию и определение общей водной разрешимой части каждого из этих chelating агентов. Это не позволяет различать свободную форму и металлическую связанную форму chelating агентов.
