SIMULTANEOUS DETERMINATION OF METAL TRACES USING SPE PRECONCENTRATION ON AMBERLITE XAD-7 BY ICP-MS IN ENVIRONMENTAL WATERS AND SAMPLES ECOTOXICOLOGY ASSESSMENT OF WATER SMAPLES AFTER MINING AND PROCESSING OF URANIUM

Popis výsledku v původním jazyce

Direct determination of extremely low concentrations of trace elements by modern spetroscopic methods is often difficult. Limitations are associated not only with insufficient sensitivity of analytical equipments, but especially with matrix interference.For this reason, preconcentration and separation of trace elements from matrix are required. This study has been conducted for the determination of nine trace elements (Be, V, Co, Ni, Y, Cd, Pb, Th and U) by inductively coupled plasma mass spectromentry(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 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 (206Pb, 207Pb, 208Pb, 232Th). The spectral interferences were eliminated by us
