Determination of Calcium Content in Xiao'er GanMao Granules by Flame Atomic Spectrometry
OBJECTIVE To establish flame atomic spectrometry method for the determination of calcium in Xi-ao'er GanMao Granules.METHODS The samples were digested by microwave digestion,Calcium content was de-termined by flame atomic absorption spectrometry.RESULTS The linear relationship of calcium was good,and the correlation coefficient was 0.999,the relative standard deviations of precision and repeatability were 1.57%and 1.16%,the recoveries were 92.5%-101%,according to the proposed limit,12 batches of sample ware unqualified in 78 batches of Xiao'er GanMao granules,the unqualified rate was 15.4%.CONCLUSION The method is accurate and can be used to determine the content of calcium in Xiao'er GanMao Granules,to provide reference for improving the quality standard of Xiao'er GanMao Granules.
