EN 16318:2013+A1:2016 Fertilizers and liming materials - Determination of chromium(VI) by photometry (method A) and by ion chromatography with spectrophotometric detection (method B)
This European Standard specifies two methods for the determination of the content of soluble chromate in fertilizers and liming materials. 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. NOTE 1 In case of reducing or oxidizing fertilizer matrix, no valid Cr(VI) content can be reported. NOTE 2 The term fertilizer is used throughout the body of this European Standard and includes liming materials unless otherwise indicated.
