| Abstract: | The sample is digested with HNO_3-HClO_4.The residue is dissolved with HCl,SrCl_2 was added as releaser to eliminate the influence of the co-existing elements.The magnesium is determined at 202.5nm and calcium is determined at 422.7nm by atomic absorption spectrometry.The method was applied to determination of calcium and magnesium in tartary buckwheat with satisfactory results. |
