Original Abstract

This study has been focused on the determination of nine trace elements 9Be, 51V, 59Co, 60Ni, 89Y, 111Cd, 208Pb, 232Th and 238U by inductively coupled plasma mass spec-trometry (ICP-MS) in natural waters and water samples after mining and processing of uranium. An ICP-MS spectrometer Agilent 7500ce, with a plasma generator of 27.12 MHz, power output of 1500 W and concentric nebulizer MicroMist with a cooled Scott chamber was used. The nonspectral interferences were eliminated by using a solution of internal standards 6Li for 9Be, 45Sc (51V), 72Ge (59Co, 60Ni, 89Y), 103Rh (111Cd), 209Bi (208Pb, 232Th, 238U). The spectral interferences were eliminated by using the Helium collision cell during meas-urement. Monitored interfering elements were K+, Na+, NH4+, Ca2+, Mg2+, Al3+, Fe3+ and Cl-, HCO3-, SO42-, PO43-. For the preconcentration polymeric sorbent Amberlite XAD-7 was used. Elements were retained as their chelates with different organic reagents: 4-(2-pyridylazo) resorcinol (PAR), 3,4-Dihydroxy-9,10-dioxo-2-anthracenesulfonic acid sodium salt (ALS), 8-Hydroxyquinoline-5-sulphonic acid (8HQS) and Ammonium pyrrolidinedithiocarbamate (APDC). The sorption process was studied under various conditions with respect to pH. Sorbents were also conditioned with different surfactants: Benzyldimethyltetradecylammo-nium chloride (Zephyramine), 1-etoxycarbonyl-pentadecyl-trimethyl-ammonium bromide (Septonex), Brij 35 or Sodium Dodecylsulphate (SDS). Various elution mixtures were also tested, the best re-sults were obtained for the mixture of acetone and ethanol (1:1) in the presence of 1 mol.l-1 HCl. The excess of acid and organic solvents were evaporated in Teflon dishes prior to the determination by ICP-MS. The Thamnocephalus platyurus as THAMNOTOXKIT FTM, Daphnia magna as a DAPHTOXKIT FTM and Artemia salina as Artoxkit MTM are organisms, which were used for ecotoxicology assessment of water samples after mining of uranium.
