摘要 目的探讨流动注射氢化物发生原子荧光法检测全血硒的方法。方法采用流动注射氢化物发生原子荧光法检测硒标准系列(1、2、4.6、8、10μg/L),观察该方法的精密度和准确度;用氢化物发生原子荧光法检测89份人全血硒.与2,3-二氨基萘荧光法的检测结果进行比较和相关性分析。结果氢化物发生原子荧光法的检出限为0.138μg/L,回收率为96.4%,相对标准偏差(RSD)在质量浓度为1μg/L时最大(4.406%),随着质量浓度的升高而减小,当质量浓度为10μg/L时降为0.512%。流动注射氢化物发生原子荧光法[(45.9±14.5)μg/L]和2,3-二氨基萘荧光法[(47.5±13.3)μg/L]检测结果之间差异无统计学意义(t=1.7878,P〉0.05),两种方法检测的结果呈高度正相关(r=0.8143,P〈0.01)。结论流动注射氢化物发生原子荧光法能够便捷、准确地测定全血含硒量,同2,3-二氨基萘荧光法检测结果一致性好。 Objective Using flowing injection hydride generation atomic fluorometric method (FI-HG-AFM) to detect the whole blood selenium content. Methods A series of standard selenium (1,2,4,6,8,10 μg/L) were dectecte by FI-HG-AFM, and the precision and accuracy of the method were observed. The selenium contents of 89 blood samples were detected by FI-HG-AFM and 2,3-diaminonaphthalene fluorometric method (DFM) respectively, and the correlation of two methods was analyzed. Results The detection limit and recovery rate of FI-HG-AFM were 0.138 μg/L and 96.4%, respectively. The relative standard deviation(RSD) was maximized at 1 μg/L(4.406%). The RSD diminished along with the increase of the concentration, and it declined to 0.512% at 10 μg/L. There was no significant difference (t = 1.7878, P 〉 0.05) between the results of FI-HG-AFM [ (45.9 ±14.5)μg/L] and DFM[ (47.5 ± 13.3)μg/L], and the two methods were in highly positive correlation(r = 0.8143, P 〈 0.01 ). Conclusions The whole blood selenium content can be rapidly and exactly detected by FI-HG-AFM, and the method are highly consistent with DFM.
