测定深裂竹根七中Cu、Zn、Cr和Mo4种金属元素的含量。采用空气-乙炔火焰原子吸收光谱法对深裂竹根七药用部位中Cu、Zn、Cr和Mo元素的含量进行测定。所建立的校准曲线相关系数r>0.9990,精密度实验RSD分别为1.3%—2.8%,重复性实验RSD分别为2.2%—2.9%,加标回收率91.0%—109.0%;方法简便快速,结果准确可靠,可用于深裂竹根七中Cu、Zn、Cr和Mo元素的含量测定。 Determination of Cu, Zn, Cr and Mo four kinds of metal elements in the content. The contents of Cu, Zn, Cr and Mo in seven medicinal parts of Phyllanthus embossed were determined by air-acetylene flame atomic absorption spectrometry. The correlation coefficient of calibration curve established was r> 0.9990, RSD of precision experiment was 1.3% -2.8%, RSD of repeatability experiment was 2.2% -2.9%, and spiked recoveries were 91.0% -109.0%. The method was simple and rapid and the results Accurate and reliable, and can be used for the determination of Cu, Zn, Cr and Mo in Septallus.
