Iodine-129 is an important radionuclide for environmental assessment, because it has a long half-life. A new analytical technique with Microwave Induced Plasma Mass Spectrometry (MIP-MS) was applied to the determination of iodine-129 (
I) in the environmental samples. Environmental samples contain a large amount of matrices elements. Therefore, the interference elements were eliminated by ashing at 1000
C, and iodine was trapped by activated charcoal and finally extracted by tetramethylammonium hydroxide (TMAH). I-129 in the soil sample was also analyzed by conventional method [neutron activation analysis (NAA)] and MIP-MS method. The analytical data by MIP-MS and NAA methods showed excellent agreement.
