Abstract
The analytical performance of the inductively coupled plasma mass spectrometry, absorption spectrophotometry and catalytic adsorptive stripping voltammetry has been compared for trace chromium determination in water samples. The following metrological characteristics were calculated: trueness, precision, linear analytical range, detection and quantification limits. The limit of detection, and the limit of quantification were calculated by the ULA method, which takes into consideration the uncertainties of the slope and the intercept of the calibration plot, designed especially for this purpose, as well as by traditional way as the 3- and 10-fold multiply of the blank standard deviation. The possibility of the speciation study of both chromium oxidation states, Cr(VI) and Cr(III), has also been considered. The ICP MS procedures were applied to the determination of total chromium in river water samples. The catalytic adsorptive stripping voltammetric method with DTPA and nitrate is sufficiently sensitive for the determination of chromium traces at the level of 0.01 to 0.1 mug/L and suitable for the chromium speciation studies.
