Abstract: This paper deals with multielement profiling of microlements in the form of their isotopes ⁹Be, ⁵¹V, ⁵⁹Co, ⁶⁰Ni, ⁸⁹Y, ¹¹¹Cd, ²⁰⁸Pb, ²³²Th, and ²³⁸U. After their complexation by 4-(2-pyridylazo)resorcinol (PAR), 3,4-dihydroxy-9,10-dioxo-2-anthracenesulfonic acid sodium salt (ALS), 8-hydroxyquinoline-5-sulphonic acid (8-HQS), and ammonium pyrrolidinedithiocarbamate (APDC), the elements were preconcentrated and separated on Amberlite XAD-16 and Amberlite SDB-L prior to their analysis by inductively coupled plasma mass spectrometry. Various parameters such as pH, eluent type and volume, presence of surfactants and volume, and matrix effects on the retention of analytes were examined. Relative standard deviation and recovery values for four replicate determinations under optimal condition were in the range of 0.2–3.6 % and 59–98 %. The proposed method was applied to the determination of elements in lake water sample and industrial water. Recovery experiments with spiked water samples were performed.

Keywords: solid phase extraction – Amberlite XAD-16 – Amberlite SDB-L – ICP-MS – industrial waters – metal contaminants
