Abstract
A simple and robust field sampling technique has been developed for the determination of chromium (III) and chromium (VI) in rivers. Water samples, on collection, were immediately passed through microcolumns of activated alumina to isolate and retain the desired species. Microcolumns were then returned to the laboratory and inserted into a FI-ICP-ES system for elution/ quantitation. Field sampling performed at 2 stations in S. Yorkshire over a 1 month period yielded elevated concentrations of chromium (III) (8–20μg/1) and chromium (VI) (1.1–4.5 μg/1) and, for each data set, the sum of the two fractions matched the total chromium concentration.
