“…Although ICPMS exhibits attractive features for the measurement of this radionuclide, the occurrence of natural iodine 127 I at substantial levels in the solutions recovered after dissolution and extraction steps was shown to induce an interference on the 129 I signal, due to the formation of a polyatomic IH 2 species, as well as a substantial matrix effect for quantitative analyses. These difficulties were overcome by analyzing diluted solutions and using 133 Cs as internal standard. The use of ICPMS after sample pretreatment allowed detection limits for 129 I in the range of 10 -4 Bq/g (10 -11 g/g).…”
