Fertilizers - Determination of chelating agents - Determination of iron chelated by o,p- EDDHA by reversed phase HPLC; German version EN 15452:2008

DIN EN 15452-2008 发布历史

This European Standard specifies a method for the chromatographic determination of the amount of iron chelated by each of the individual isomers of the chelating agent ortho-para EDDHA (O,p-EDDHA) in fertilizers The method allows the identification of this chelating agent and the determination of the water soluble fraction of iron chelated by this chelating agent, The method is not applicable for the determination of the amount of free chelating agent NOTE 1 This method has been shown to be also suitable for the determination of the amount of iron chelated by each of the individ ual isomers of the chelating agent ortho-ortho EDDHA (o,o-EDDHA) in fertilizers. NOTE 2 O,o-EDDHA and o,p-EDDHA are abbreviations used in this European Standard for the sake of simplicity, For complete names see Annex C. NOTE 3 The substances O,o-EDDHA and O,p-EDDHA both exist as different stereoisomers. For O,o-EDDHA a meso form and a d/I pair (the racemic isomers) exist, for O,p-EDDHA two different d/I pairs exist. All four stereoisomers are observed separately in this method. NOTE 4 Cur en iy an analyticaqly pure standard only exists for o,o-EDDHA. The method for O,p-EDDHA has been developed with an O,p-EDDHA standard containing an uncertain concentration of O,p-EDDHA.
