摘　　要：目的:建立一种同时测定中蒙药苦杏仁药材中F-、Cl-、Br-、NO_3^-、SO_4^(2-)、PO_4^(3-)阴离子的含量测定方法。方法:采用离子色谱法、阴离子色谱柱、氢氧化钠梯度淋洗、电导检测苦杏仁6种无机阴离子。结果:F-、Cl-、Br-、NO_3^-、SO_4^(2-)、PO_4^(3-)的加样回收率介于97%~102%,苦杏仁中F-、Cl-、Br-、NO_3^-、SO_4^(2-)、PO_4^(3-)重复性良好,含量分别为0.057%0.084%,0.063%,0.070%,0.30%,0.12%。结论:离子色谱法可以同时检测苦杏仁中6种阴离子,灵敏度高,结果准确可行,为苦杏仁的质量控制提供了一种简便快速的方法.Objective：To establish a method for the simultaneous determination of Amygdalin in Mongolian medicine herbs Cl^-,Br^-,NO3^-,SO4^2-,determination of PO3-4anions.Methods：Using ion chromatography,gradient elution of sodium hydroxide,almond conductivity detection,6 kinds of inorganic anions.Results：F^-,Cl^-,Br^-,NO3^-,SO4^2-,PO4^3- and the recovery rate is between 97%-102%,the bitter almond F^-,Cl^-,Br^-,NO3^-,SO4^2-,PO4^3-,have good repeatability,the contents were0.057%,0.084%,0.063%,0.070%,0.30%,012%.Conclusion：Ion chromatography at detection of 5 anions,bitter almond,high sensitivity,accurate and feasible,and provides a simple and rapid method for the quality control of bitter almond.
