    Abstract: 長久以來環境中核種偵測以放射性活度度量,然而,核種之比活度低、半衰期長,傳統方法偵測不易,如I-129半衰期為1.57*10/sup 7/年須經多次濃縮後才能以傳統方法偵測,且I-129為核武測試和核燃料製造時U-235和Pu-239之分裂產生,碘-129經大氣、海洋、雨水及食物互相遷移,又半衰期長不斷累積於環境中。因此,碘-129應長期監測其放射劑量。本研究擬以感應耦合電漿質譜儀分析法( Inductively coupled plasma mass spectrometry, ICP -MS)應用於核種分析, ICP-MS為一微量同位素及多元素分析技術,具有許多優點;低偵測極限、分析時間短、簡單質譜等。本研究之目的在於探討磁場式高解析ICP-MS偵測核電廠廢水中I-129之可行性。結果顯示:以Iodine- 2000樹脂在4MK/sub 2/CO/sub 3/溶液調理下,I-129被樹脂吸附時不受海水之影響。ICP-MS檢測濃度之線性範圍:0- 1.26 ng/mL,偵測極限為9pg/mL。以ICP-MS偵測廢水中I-129之步驟加以討論敘述,且可行性高。
