【摘要】 建立了同时测定某混合炸药中RDX与FOX–7组分含量的高效液相色谱法。优化后的色谱条件:采用C₁₈色谱柱（150 mm×4.6 mm,5 μm）,检测波长为210 nm,流动相为乙腈–水（60∶40）,柱温为25 ℃,流量为1.0 mL/min,进样体积为2 μL。RDX的质量浓度在0.12～0.72 mg/mL范围内与色谱峰面积线性关系良好,相关系数为0.999 9,FOX–7的质量浓度在0.24～1.44 mg/mL范围内与色谱峰面积线性关系良好,相关系数为0.998 0。RDX、FOX–7的平均回收率分别为99.5%和100.5%,相对标准偏差分别为0.490%和0.258%（n=6）。该方法可应用于实际组分检测中。更多还原

【Abstract】 A high performance liquid chromatography （HPLC） method was developed for the simultaneous determination of RDX and FOX–7 in a mixed explosive.The optimized chromatographic conditions were as follows:C₁₈ column （150 mm×4.6 mm,5 μm）,detection wavelength was 210 nm,mobile phase was acetonitrile/water （60∶40）,column temperature was 25 ℃,flow rate was 1.0 mL/min,injection volume was 2 μL.The linear range of RDX was 0.12–0.72 mg/mL,and the correlation coefficient was 0.999 9.The linear range of FOX–7 was 0.24–1.44 mg/mL,and the correlation coefficient was 0.998 0.The average recoveries of RDX and FOX–7 were 99.5% and 100.5%,respectively,and the relative standard deviations were 0.490% and 0.258% （n=6）,respectively.The method can be applied to the actual component detection.更多还原
