火焰原子吸收光谱法测定中成药中微量元素

Determination of Trace Elements in Chinese Traditional Medicine by Flame Atomic Absorption Spectrome

摘要: 利用火焰原子吸收光谱法测定了中成药复方半夏片中14种微量元素.Ca、Mg、Fe、Zn、K、Na、Mn、Cu、Co、Sr、Cr、N i、Cd、Pb的含量分别为365.4、162.0、1 035.8、24.74、599.9、149.1、42.1、22.8、3.88、12.8、20.26、7.15和10.77μg.g-1,Cd未检出.详细研究了消化液种类、HNO3和HC lO4的比例、消化体积及消化时间对测定结果的影响.

Abstract: The fufangbanxia tables were digested with HNO_3-HCl mixed acid and fourteen trace elements in digested solution were determined by flame atomic adsorption spectrometry.The content of calcium,magnesium,iron,zinc,potassium,sodium,manganese,copper,cobalt,strontium,chromium,nickel,and lead in fufangbanxia tables were 365.4,162.0,1035.8,24.74,599.9,149.1,42.1,22.8,3.88,12.8,20.26,7.15 and 10.77 μg·g~(-1),respectively.No cadmium component was detected.The effects of mixed acid,the ratio of HNO_3 to HCl in mixed ...
