摘要
目的:建立阿戈美拉汀原料中镍残留量的检测方法。方法:采用火焰原子吸收分光光度法,以吡咯烷二硫代氨基甲酸铵-甲基异丁基酮体系萃取富集制备样品,在232.0 nm波长处测定吸光度,按外标法计算镍含量。结果:镍在0.05~4.00μg·ml-1浓度范围内有良好的线性关系(r=0.999 0),平均回收率为93.3%。结论:该法简便快捷,重复性好,能准确测定阿戈美拉汀原料中镍残留量。
Objective: To develop a method for the determination of nickel in agomelatine.Method: The flame atomic absorption spectrometry was applied to determine the content of nickel in agomelatine enriched by the solvent system of ammonium pyrrolidinedithiocarbamate(APDC)-methyl isobutyl ketone(MIBK)at 232.0 nm.The external standard method was performed to calculate the sample concentration.Result: The linear range of nickel was 0.05-4.00 μg·ml-1(r=0.999 0).The average recovery was 93.3%.Conclusion: The method is simple,accurate and rapid,and it can be used in the quality control of agomelatine.
