Fertilizers. Determination of trace elements. Determination of chromium(VI) by photometry (method A) and by ion chromatography with spectrophotometric detection (method B)

PUBLISH DATE 2012

PAGES 20

This Technical Specification specifies two methods for the determination of the content of soluble chromate in fertilisers.

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: In case of reducing or oxidising fertiliser matrix, no valid Cr(VI) content can be reported.
