This European Standard specifies two methods for the determination of the cadmium content of solid, mineral fertilizers, and rock phosphates, after extraction with nitric acid. Organic fertilizers are not included in this standard. Taking into account that Flame AAS and ICP-OES are widespread and commonly used techniques, it was decided to incorporate both detection techniques in this Standard. Method A - Determination of the cadmium content by flame atomic absorption spectrometry (flame AAS). Method B - Determination of the cadmium content by inductively coupled plasma-optical emission spectrometry (ICP-OES). However, due to the limits of quantification of the detection techniques, both methods are applicable for cadmium contents not less than 1 mg/kg. Many of the procedures and reagents are common for both methods.
