✦ Synopsis

The determination of chromium by atomic absorption spectrometry (a-a-s.) does not discriminate between the various oxidation states of the element. Recently, a method was required for the rapid dctcrmination of the concentrations of each of the two main oxidation states of chromium in soil cstracts, and this was achieved by combining total anion exchange with a.a.s.

Experiixen tal

AQQUratUS

An EEL 240 atomic absorption spectrophotomcter was used with ailacetylene and nitrous oxidcacetylsns burners. and a chromium hollowcathode lamp operated at 10 mA.

In the flow system described, iron(I1) is measured spectrophotometrically with l,lO-phenanthroline, and total iron is determined in the same flow line by atomic absorption spectrometry. Linear calibration ranges are 0.1-35 and 0.1-10 rg ml-' for iron and total iron, respectively.
