摘要
目的用原子荧光分析法对陶瓷餐具中锑的含量进行分析与讨论。方法用原子荧光分析法与孔雀绿法分光光度法(GB 31604.41—2016)分别对陶瓷餐具(10宗)中的锑含量进行测定。结果用原子荧光分析法与孔雀绿法分光光度法分别对陶瓷餐具中锑的测定结果进行比较,结果表明原子荧光分析仪与孔雀绿分光法结果一致;锑线性范围为0 ng/ml～100 ng/ml,相关系数为0.999,回收率在92.0%～100.0%,相对标准偏差为1.18%～1.28%。结论本文用原子荧光分析仪对陶瓷餐具中锑含量进行测定的方法具有准确、干扰少、灵敏、快速等优点。
Objective To determine antimony in ceramic dishware by atomic fluorescence spectrometry. Methods Determination of cerium content in ceramic tableware(10 cases) was conducted by atomic fluorescence spectrometry and malachite green spectrophotometry(GB 31604.41-2016). Results The determination results of antimony in ceramic dishware respectively by atomic fluorescence spectrometry and malachite green spectrophotometry were compared. The result by atomic fluorescence analyzer was consistent with the results by malachite green spectroscopy. The linear range was within 0 ng/ml-100 ng/ml, and the correlation coefficient was 0.999. The recovery rate was within 92.0%-100.0%. Relative standard deviation was within 1.18%-1.28%. Conclusion Atomic fluorescence analyzer has advantages of accuracy, less interference, sensitivity, and rapidity in detecting antimony content in ceramic dishware.
