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.
