摘要

The study describes the application of new methodologies for the simultaneous determination of As(III)/As (V), Sb(III)/Sb(V) and Tl(I)/Tl(III) ions in waters and bottom sediments of the Klodnica River (Poland) with the hyphenated technique of high-performance liquid chromatography-inductively coupled plasma-mass spectrometry (HPLC-ICP-MS). Time and spatial correlations were determined in the changes of total and speciation concentrations of the above-mentioned analytes in Klodnica river in 2012. The developed methodologies demonstrate high selectivity and limits of quantification at the level of 0.009-0.120 mu g/L. Their repeatability, precision and recovery are appropriate for trace analyses of environmental samples. Time and spatial correlations, and concentrations of inorganic As, Sb and Tl ions demonstrated high variability both in water and bottom sediments.
