本文叙述了用反相高效液相色谱法分离分析9/(单基火药中的安定剂二苯胺,以Zorbax DOS柱,甲醇/水(95:5V/V)为流动相,用光电二极管阵列检测器,检出二苯胺和分解产物的光谱一色谱三维图进行定性,并观察单基火药随存放过程的增长而变化的情况,用SPD—2AS,UV检测器和C—R 2AX微处理机,外标法定量,标准偏差为7.5×10~(-3),2.2×10~(-2),相对误差为-0.47％,变异系数为0.52,1.79,回收率可达99.62％,由分析结果可见本法的准确度和精密度,均令人满意,分析时间可缩短至几分钟。
This article describes the separation and analysis of 9 / (diphenylamine, a stabilizer based on a single base gunpowder, using a Zorbax DOS column and methanol / water (95: 5 V / V)) as the mobile phase by reversed-phase high performance liquid chromatography with a photodiode array The detection of diphenylamine and decomposition products by spectrophotometry three-dimensional map qualitative, and to observe the single-base gunpowder with the growth of storage process changes, using SPD-2AS, UV detector and C-R 2AX microprocessor, The standard deviation was 7.5 × 10 -3 and 2.2 × 10 -2, the relative error was -0.47%, the coefficient of variation was 0.52 and 1.79, and the recovery rate was 99.62% This method shows the accuracy and precision, are satisfactory, analysis time can be shortened to a few minutes.
