Dissolved chromium(VI) in water according to EN ISO 18724
Summary
Hexavalent chromium (Cr(VI)) can originate from natural geological sources or from contamination caused by industrial activities such as metal plating or leather tanning. Due to its toxicity and carcinogenicity, hexavalent chromium is regulated in environmental waters and requires reliable monitoring. EN ISO 18724 describes the photometric determination of Cr(VI) in water using various methods including ion chromatography with post-column reaction (IC-PCR). This Application Note demonstrates the analysis of Cr(VI) in drinking water samples using IC-PCR in accordance with the procedure outlined in Appendix C, Section C.4 of EN ISO 18724.
