| Abstract: | 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. |
