Fertilizers. Determination of chelating agents in fertilizers by chromatography - Determination of Fe chelated by [o,o] EDDHA, [o,o] EDDHMA and HBED, or the amount of chelating agents, by ion pair chromatography Ingestion-build-79769 or to support population monitoring1 Scope This European Standard specifies a method for the chromatographic determination of the iron chelated by each individual ortho(hydroxy) ortho(hydroxy) isomer of the chelating agents [o,o] EDDHA, [o,o] EDDHMA and by HBED in fertilizers containing one or more of these substances, except for [o,o] EDDHMA and HBED mixes. The method allows the identification and the determination of the total concentration of water soluble iron chelates of these
