摘要
提出了反相高效液相色谱法测定高能发射药中5种组分硝化甘油(NG)、黑索今(RDX)、硝基胍(NQ)、Ⅱ号中定剂(C2)和邻苯二甲酸二正辛酯(DOP)的含量。试样溶解后进行色谱分离,采用Agilent色谱柱(150mm×4.6mm,5μm),流动相为甲醇-水(60+40)混合溶液(用于分离NG、RDX、NQ和C2)和甲醇-水(95+5)混合溶液(用于分离DOP),在波长220nm处进行测定。NG的质量浓度在0.42～4.08g.L-1,RDX在1.41～5.04g.L-1,NQ在1.11～3.74g.L-1,C2在0.07～0.90g.L-1,DOP在0.08～0.37g.L-1时分别与其峰面积呈线性关系。5种化合物的加标回收率在99.3%～101.9%之间;相对标准偏差(n=6)在0.19%～3.1%之间。
RP-HPLC was applied to the determination of 5 components, including nitro glycerol （NG）, hexogen （RDX）, nitroguanidine （NO.）, centralite Ⅱ （（32） and dioctyl o phthalate （DOP） in high energy gun propellant. The sample after dissolution was separated by using Agilent column （150 mm ）〈 4. 6 mm, 5 μm） as stationary phase, and a mixture of CH3OH-H2O （60＋40） as mobile phase for NG, RDX, NQ and C2, and mixture of CH3OH-H20 （95＋5） as mobile phase for DOP. The contents of the 5 components were determined at the wavelength 220 nrn. Linear relationships between values of peak area and mass concentration of NG, RDX, NQ, Ce and DOP were kept in ranges of 0. 42-4. 08 g · L^-1 , 1.41-5.04 g · L^-1 , 1.11-3.74 g · L^-1 , 0. 07-0. 90 g · L^-1, 0.08-0.37 g · L^-1 , respectively. Tests for recovery and precision were made by standard addition method. Values of recovery and RSD＇ s （n = 6） found were in the range of 99. 3%- 101. 9% and 0. 19% - 3. 1%, respectively.
