Summary
This European Standard specifies two methods for the determination of soluble chromate in fertilizers. Method A specifies the determination of chromate after extraction with water by photometry. This method can be used to determine Cr (VI)-mass fractions in solids higher than 1 mg/kg. Method B specifies the determination of chromate by alkaline digestion and ion chromatography with spectrophotometric detection. This method can be used to determine Cr (VI)-mass fractions in solids higher than 0,1 mg/kg. In case of recucing or oxidizing fertilizer matrix, no valid Cr (VI) content can be reported.
