摘要
采用原子吸收光谱法测定了多维元素药片中矿物质含量。样品用硝酸消解,用火焰原子吸收法测定钙、镁、钾、铜、铁、锰,用石墨炉原子吸收法测铬和镍。方法灵敏可靠,测量相对标准偏差<2.4%,回收率在90%～100%之间,能满足药品检测要求。
To detect mineral component in multi-elements medicinal tablet using atomic absorption spectrometry. Samples was digested by HNO_3, to detect Ca, Mg, K, Cu, Fe, Mn in flame atomic absorption, to detect Cr and Ni in graphite atomic absorption. This method was sensitive and simple. Relative standard deviation was less 2.4%, recovery rate was between 90% and 100%.
