Analysis Method of Dissolved Hexavalent Chromium According to EPA218.6

User Benefits

- Trace concentrations of hexavalent chromium (Cr (VI)) can be analyzed according to EPA 218.6. - Cr(VI) is chromatographically separated from potential interferences and selectively detected using post-column derivatization.

Introduction

The method for analyzing dissolved Cr(VI) in drinking water, groundwater, and industrial wastewater is described in EPA 218.6. This article demonstrates analysis of Cr(VI) with the Shimadzu Prominence Inert System. Dissolved Cr(VI) is separated by an anion exchange column. The colored complex formed between Cr(VI) and diphenylcarbazide in the post-column derivation is then detected at 530 nm.
