Water quality — Determination of dissolved chromium(VI) in water — Photometric method

Qualité de l'eau — Détermination du chrome dissous(VI) dans l'eau — Méthode photométrique

Abstract / scope

This document specifies a method for the photometric determination of dissolved chromium(VI) using manual, (e.g. hand photometry), automated static (e.g. discrete analyser system) or automated dynamic [e.g. flow injection analysis (FIA), continuous flow analysis (CFA)] or ion chromatography with post-column reaction (IC-PCR)] techniques.

The method described in this document is applicable for other matrices, such as leachates from landfills and raw wastewater, after appropriate method validation.
