反相高效液相色谱法分析溶液中的ADN含量

Determination of ADN in Solution by RP-HPLC

采用反相高效液相色谱法建立了溶液中二硝酰胺铵(ADN)的分析测定方法。选用色谱条件为:Phenomenex Gemini C 18 色谱柱,0.1%(质量分数)三氟乙酸水溶液-甲醇为流动相,流速1 mL/min,分别在紫外280 nm和230 nm处检测ADN和硝酸铵(AN),通过反相高效液相色谱法分析获得了ADN的含量。分析结果为:ADN和AN的质量浓度分别为30 155.144 mg/mL和275 039.814 mg/L,其质量浓度的相对标准偏差(RSD)分别为1.290%和1.949%。该方法分析结果重复性好,准确可靠,可用于ADN溶液的定性与定量分析。

Analytical method for determination of ammonium dinitramide(ADN) in solution was established using reversed- phase high perfor- mance liquid chromatography (RP-HPLC). The chromatographic column Phenomenex Gemini C 18 column was used. The mobile phase was A (0.1% trifluoroacetic acid solution)-B (methanol) with a flow rate of 1mL/min. The detection wavelengths were 280 nm for ADN and 230 nm for ammonium nitrate(AN), respectively. Under the chromatographic conditions, the content of ADN was analyzed. The analytical results show that the mass concentrations of ADN and AN are 30 155.144 mg/L and 275 039.814 mg/L, and the relative standard deviations (RSD) of their mass concentrations are 1.290% and 1.949%, respectively. The analytical results of this method are reproducible, accurate and reliable, and can be used for the qualitative and quantitative analysis of ADN solutions.
