摘　　要：利用离子色谱技术建立了新型单质炸药3,4-二硝基呋咱(DNTF)中常见阴阳离子的分析方法,对DNTF精制前后常见阴阳离子进行了定量分析,粗品中阴阳离子含量(μg.g-1)分别为:Na+(53.3),Mg2+(5.5),Ca2+(32.4),HCOO-(2.46),Cl-(1.28),NO2-(12.8),NO3-(28.2)。The analytical method of trace ionic impurities in 3,4-Dinitrofurazan （DNTF） was established using ion chromatography considering their significant effect up on the quantity control in this explosive preparation process. Precise quantitative determination of anions and cations existing in DNTF with and without refining had been performed. The concentrations of Na＋, Mg2＋, Ca2＋, HCOO-, Cl-, NO-2, and NO-3 in crude sample are 53.3,5.5,2.4,2.6,1.8,2.8,8.2 μg·g-1, respectively, while those of the corresponding ions were obviously reduced after the product was refined.
