摘　　要：将微量脉冲进样技术和火焰原子吸收光谱法结合，对钝顶螺旋藻中的Ni，Zn，Mn，Cu，Mg，Fe，Ca和Pb等微量元素进行了测定。结果显示钝顶螺旋藻含有丰富的镁，锌，铁及钙，铜。该方法的加标回收率为96．58％～106．12%，RSD〈4．26%，具有良好的准确度和精密度。测定结果可为探讨钝顶螺旋藻中微量元素含量与其药效的相关性提供科学数据。The contents of trace elements Ni, Zn, Mn, Cu, Mg, Fe, Ca and Pb in Spirulina platensis （Notdst.） Geitl. were determined by flame atomic absorption spectrometry combined with microsampling pulse nebulization technique. The results of the determination show that Spirulina platensis （Notdst.） Geitl. are rich in the inorganic elements such as Mg, Zn, Fe, Ca and Cu. Its recovery ratio obtained by standard addition method ranged between 96. 58% and 106.12%, and its RSD was lower than 4. 26%. The result will provide scientific data for the study on the trace elements in Spirulina platensis （Notdst.） Geitl. and on their relativity of efficacy of medicine.
