| 摘 要： | 建立了烟火药剂中苦味酸的高效液相色谱检测方法。采用Zorbax Eclipse XDB-C18色谱柱（4.6mm×250mm,5μm）分离,V（甲醇）∶V（0.1%冰醋酸水溶液）=55∶45,等梯度洗脱,流速0.8mL/min;测定温度为40℃;采用紫外检测器检测,检测波长为350nm。苦味酸的质量浓度在0.5—20mg/L时与色谱峰面积之间线性关系良好（r=0.9998）;加标回收率为85.6%—92.4%,相对标准偏差（RSD）为2.1%—6.5%。该方法简便快速,结果准确,重现性好,可作为检测烟火药剂中苦味酸的一个有效方法。 |

| Abstract: | A method for the determination of picric acid in pyrotechnic composition by high performance liquid chromatography was developed.The separation were performed on a Zorbax Eclipse XDB-C18 column（4.6mm×250mm,5μm）with methanol-0.1% acetic acid solution（volume ratio of 55∶45） as the mobile phase at the flow rate of 0.8mL/min and the temperature of 40℃.The detection wavelength was 350nm for ultraviolet detector.There were good linear relationships between the mass concentration and the peak areas of picric acid in the range of 0.5—20mg/L（r=0.9998）.The recoveries were 85.6%—92.4% with the relative standard deviations of 2.1%—6.5%.The method is quick,simple with accurate results and good repeatability,and can be used for the determination of picric acid in pyrotechnic composition. |
