摘要
本实验建立了钯－硝酸镁基体改进剂石墨炉原子吸收光谱法测定六味地黄丸中锡的方法。研究了基体改进剂的加入方式对测定的影响。方法的相对标准偏差为２．５％，回收率在９０％～１１０％之间，检出限为０．３ｎｇ／ｍＬ。本方法可用于中成药中锡的测定。
A graphite furnace atomic absorption spectrometric method for the determination of tin in traditional Chimese drug〃 Liuwei Dihuang Wan〃is described.A mixture of palladium and magnesium nitrate is used as a matrix modifier.A special procedure for the application of the matrix modifier has been employed.The detection limit is 0.3ng/mL,and the relative standard deviation is 2.5%,The recovery is in the range of 90%～110%.
