| 摘 要： | 利用流动注射-化学发光法测定啤酒中痕量铬，采用正交设计试验找出了最佳测定条件。结果表明本法具有操作简便、测量快速、灵敏度高、稳定性好等优点，并已被成功地用于啤酒中痕量铬的测定。方法的线性范围为1×10-6～1×10-9kg／L，检出限为8.2×10-12kg／L，回收率为96．3％，与标准方法相比，测定结果无显著性差异（P＞0·05）。

| Abstract: | A new mothod for the determinationof Cr3+ by flow injection analysis-chemiluminescenceanalysis is proposed in the paper. The optimal condition was found by right-cross test. This method israpid, simple, stable and sensitive and has been successfully applied to determinate chromium in beer.The linear range is 1 ｘ 10-6~ 1 ｘ10-9g/ml, limit ofdetection is 8. 2 ｘ 10-12g/ml, recovery is 96. 3%.The results obtained with the proposed method arewell in agreement with those of the standardmethod. |
