| 英文摘要 | Hollow cathode lamps (HCL) are the most commonly used excitation sources for hydride generation-atomic fluorescence spectrometry (HG-AFS). In general, there was lead (Pb) interference in selenium (Se) HCL. This kind of light source interference affected the accuracy of the detection results when Se and Pb simultaneously were determined by HG-AFS. In this work, the effects of light source interference were discussed and analyzed, and a light source interference factor method was proposed to correct the spectral interference. This method had many advantages including simple operation and high reliability, and appropriately reduced the purity of the cathode of the light source. The spectral interference of Se HCL was discussed. The conditions of simultaneous determination of Se and Pb in K-3[Fe(CN)(6)]-KBH4-HCl chemical generation system were optimized, and the influence of Pb interference in HCL of Se was discussed. In the concentration range of 2-50 mu g/L, the detection limit of Se was 0.034 mu g/L (r = 0.9995), and the detection limit of Pb was 0.019 mu g/L (r = 0.9997). The method precisions were 0. 85% (10 mu g/L, Se, n =9) and 0.47% (10 mu g/L, Pb, n = 9), respectively. The feasibility of the method was confirmed by the simultaneous detection of national standard sample rice GBW10010 (GSB-1), wheat GBW10011 (GSB-2) and soy flour. The results of the light source calibration were consistent with the standard values. |
