A sensitive method is described for the determination of Mo in plasma or serum by graphite furnace atomic absorption spectrometry. The method involves extraction of the metal as the 8-hydroxyquinoline complex and is free of the interference effects that prevent the direct analysis of plasma for Mo. Recoveries of internal standards were excellent and results from the analysis of a National Institute of Standards and Technology Standard Reference Material were in good agreement with certified values. The sensitivity of the method, based on the analysis of 1 ml of plasma, is ca. 3 ng ml-1.
本文描述了一种通过石墨炉原子吸收光谱法测定血浆或血清中钼的灵敏方法。该方法涉及将金属作为8-羟基喹啉络合物进行萃取，且不存在妨碍直接分析血浆中钼的干扰效应。内标物的回收率极佳，对国家标准与技术研究院标准参考物质的分析结果与认证值高度吻合。基于对1毫升血浆的分析，该方法的灵敏度约为3纳克/毫升。
