目的：建立螺旋藻类保健品中铜,砷,镉,汞,铅5种重金属元素含量的测定方法。方法：微波消解法处理样品,用电感耦合等离子体质谱法( ICP-MS)检测螺旋藻类保健品中5种重金属元素的含量。结果：铜,砷,镉,汞,铅5种元素的最低检出限分别为6.72,6.25,3.12,0.331,8.78 ng·g-1；在各自的浓度范围内线性关系良好( r均大于0.9997)；加样回收率分别为110.4%,96.6%,93.1%,102.8%,101.4%,RSD 分别为3.2%,4.2%,2.5%,2.9%,3.0%(n=9)。结论：该方法准确、灵敏、简便,适用于螺旋藻类保健品中有害重金属元素的检测。
目的：建立螺鏇藻類保健品中銅,砷,鎘,汞,鉛5種重金屬元素含量的測定方法。方法：微波消解法處理樣品,用電感耦閤等離子體質譜法( ICP-MS)檢測螺鏇藻類保健品中5種重金屬元素的含量。結果：銅,砷,鎘,汞,鉛5種元素的最低檢齣限分彆為6.72,6.25,3.12,0.331,8.78 ng·g-1；在各自的濃度範圍內線性關繫良好( r均大于0.9997)；加樣迴收率分彆為110.4%,96.6%,93.1%,102.8%,101.4%,RSD 分彆為3.2%,4.2%,2.5%,2.9%,3.0%(n=9)。結論：該方法準確、靈敏、簡便,適用于螺鏇藻類保健品中有害重金屬元素的檢測。
목적：건립라선조류보건품중동,신,력,홍,연5충중금속원소함량적측정방법。방법：미파소해법처리양품,용전감우합등리자체질보법( ICP-MS)검측라선조류보건품중5충중금속원소적함량。결과：동,신,력,홍,연5충원소적최저검출한분별위6.72,6.25,3.12,0.331,8.78 ng·g-1；재각자적농도범위내선성관계량호( r균대우0.9997)；가양회수솔분별위110.4%,96.6%,93.1%,102.8%,101.4%,RSD 분별위3.2%,4.2%,2.5%,2.9%,3.0%(n=9)。결론：해방법준학、령민、간편,괄용우라선조류보건품중유해중금속원소적검측。
Objective:To establish a method for the determination of Cu,As,Cd,Hg and Pb in spirulina health products. Meth-ods:The samples were digested by microwave and determined by ICP-MS. Results: The minimum detection limits of Cu,As,Cd,Hg and Pb was 6. 72,6. 25,3. 12,0. 331 and 8. 78 ng·g-1 , respectively, and showed good linear relationship within respective concentra-tion range (r >0. 999 7) with the average recovery of 110.4%,96.6%,93.1%,102.8%, 101.4% and RSD of 3.2%,4.2%, 2. 5%,2. 9%,3. 0%(n=9), respectively. Conclusion:The method is sensitive, simple and accurate, and can be used to determine the harmful elements in spirulina health products.
