摘要
目的建立多种微量元素注射液Ⅰ和Ⅱ中硒的测定方法.方法供试品经25%盐酸溶液稀释,采用流动注射氢化物发生原子吸收分光光度法测定硒含量.结果本法检出限为0.30μg·L-1,方法的线性范围为0~40μg·L-1,回收率分别为96%~99%,变异系数RSD<3%.结论该方法操作简便、快速、灵敏、单次测定样品量大,可以用于多种微量元素注射液中硒的质量控制.
Objective To establish a method for the determination of selenium in multi-trace elements injection Ⅰ and Ⅱ.Methods The sample that was diluted by 25% HCl was determined by the flow injection hydride generation atomic absorption spectrometry.Results The detection limit of this method was 0.30 μg·L-1,the linear range was 0~40 μg·L-1 and the recovery was in the range of 90%~99%,RSD〈3 %.Conclusion The method was simple,rapid,sensitive and had a large quantity of samples determined at one time,and it can be used for the quality control of selenium in multi-trace elements injection.
