3,3‐Diamino‐4,4‐azoxyfurazan (DAAF) as a promising energetic material, has many potential applications in both civil and military areas. High‐performance liquid chromatography (HPLC) is an important analytical method for quality control and environmental monitoring of DAAF. In this study, chromatographic conditions of DAAF were optimized to develop an analytical method based on HPLC‐DAD. DAAF and its byproducts were separated within 13 min with DAAF's retention time of 8.690 min and the resolution of all peaks were above 1.5 with high number of theoretical plates (N>54259) under optimum condition of HPLC. Meanwhile, the method was validated and showed good performance for quantitative analysis of DAAF with LOD of 0.19 ng and linearity range from 0.84 to 211.16 μg mL⁻¹. Furthermore, the method was applied to the analysis of the purity of DAAF for quality control of different preparation stages and trace DAAF in wastewater for environmental monitoring around explosive manufacturing.

DAAF HPLC方法的开发，验证及其在质量控制和环境监测中的应用

3,3-二氨基-4,4-偶氮呋喃（DAAF）作为一种有前途的高能材料，在民用和军事领域都有许多潜在的应用。高效液相色谱（HPLC）是DAAF的质量控制和环境监测的重要分析方法。在本研究中，优化了DAAF的色谱条件，以开发基于HPLC-DAD的分析方法。DAAF及其副产物在13分钟内被分离，DAAF的保留时间为8.690 min，并且在最佳HPLC条件下，使用大量理论塔板（N> 54259），所有峰的分离度均高于1.5。同时，该方法经过验证，对于定量分析DAAF（LOD为0.19 ng，线性范围为0.84至211.16μgmL ^-1）显示出良好的性能。。此外，该方法还用于分析DAAF的纯度，以控制不同制备阶段的质量，并用于分析废水中的痕量DAAF，以用于炸药制造周围的环境监测。
