Cation exchange resin%ICP-MS%Soil%Trace iodine
土壤样品碱熔后，采用阳离子树脂进行静态交换，电感耦合等离子体质谱法（ICP-MS）作为分析方法检测土壤中的微量碘。方法检出限为0.018×10-6，变异系数（RSD，n=6)为0.51%~4.17%，加标回收率在93.79%~107.73%之间，测定结果准确可靠、满足分析要求。
土壤樣品堿鎔後，採用暘離子樹脂進行靜態交換，電感耦閤等離子體質譜法（ICP-MS）作為分析方法檢測土壤中的微量碘。方法檢齣限為0.018×10-6，變異繫數（RSD，n=6)為0.51%~4.17%，加標迴收率在93.79%~107.73%之間，測定結果準確可靠、滿足分析要求。
토양양품감용후，채용양리자수지진행정태교환，전감우합등리자체질보법（ICP-MS）작위분석방법검측토양중적미량전。방법검출한위0.018×10-6，변이계수（RSD，n=6)위0.51%~4.17%，가표회수솔재93.79%~107.73%지간，측정결과준학가고、만족분석요구。
After the alkali-melting process treated the soil sample,cation resin was used for static exchange,then trace iodine in soil was determined by ICP-MS. The method detection limit was 0.018×10-6, the variation coefficient (RSD=6) was 0.51%~4.17%,the recovery rate of standard addition was 93.79%~107.73%,the result is quite accurate and satisfied.
