SIMULTANEOUS DETERMINATION OF METAL TRACES BY ICP-MS IN ENVIRONMENTAL WATERS USING SPE PRECONCENTRATION ON DIFFERENT POLYMERIC SORBENTS
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
