摘要
叠氮含能化合物废水用碱中和后,采用高效液相色谱法和分光光度法分别测定其中叠氮含能化合物DIANP、二甲亚砜(DMSO)、NaN3的含量。HPLC测定条件:YWG C18柱(150 mm×4.6 mm,10μm),以甲醇和水作为流动相,梯度洗脱,流速1 mL/min,检测波长230 nm。分光光度法测定条件:显色剂为FeCl3,pH 2～3时显色,检测波长460 nm。结果表明,DIANP回收率为97.8%～100.9%,RSD=1.2%(n=5),检出限为1.5 mg/L,标准曲线的线性回归系数r=0.997 7,线性范围为17～859 mg/L;DMSO回收率98.2%～101.9%,RSD=1.5%(n=5);NaN3回收率98.9%～100.5%,RSD=0.6%(n=5),检出限为1.5 mg/L,标准曲线的线性回归系数r=0.999 1,线性范围为5.7～57.0 mg/L,表观摩尔吸光系数901 L/(mol.cm)。该方法已经应用于实际生产线废水的检测和治理,效果良好。
The method for determining the components in a energetic azid wastewater was established.DIANP was determinated by HPLC with UV detection.The HPLC separation was performed on a YWG C18 column（150 mm×4.6 mm,10 μm） with methanol and water as the mobile phase at a flow rate of 1.0 mL/min.The detection wavelength were 230 nm.The spectrophotometer conditions were as follows：FeCl3 solution,pH 2~3,the detection wavelength were 460 nm.The recovery of DIANP was 97.8%～100.9% with a RSD of 1.2%（n=5）,the limits of detection was 1.5 mg/L,the linear range was 17～859 mg/L.The recovery of DMSO was 98.2%～101.9% with a RSD of 1.5%（n=5）.The recovery of NaN3 was 98.9%～100.5% with a RSD of 0.6%（n=5）,the limits of detection was 1.5 mg/L,the linear range was 5.7～57.0 mg/L,the apparent absorptivity was 901 L/（mol·cm） at 460 nm.The method was applied to actual samples.
