摘要
基于正丁醚在纳米氧化锌材料表面的催化发光现象设计并制造了正丁醚催化发光传感器,并提出了一种快速测定空气中正丁醚的方法。在检测波长为440nm,反应温度为288℃,载气流量为280mL·min-1条件下,正丁醚的质量浓度在30.0~2 000mg·m-3内与其催化发光强度呈线性关系,检出限(3S/N)为12.0mg·m-3。将上述方法用于空气样品中正丁醚含量的测定,其测定结果与气相色谱-质谱法所得结果吻合。
A sensor for n-butyl ether was designed and fabricated based on the cataluminescence (CTL) action at the surface of nano-ZnO, and a method for rapid determination of n-butyl ether in air was proposed. At the detection wavelength of 440 nm, and under reaction temperature of 288 ℃, with air flowrate of 280 mL · min ^-1, linear relationship between the CTL intensities and mass concentrations of n-butyl ether was found in the range of 30.0-2 000 mg · m^- 3, with detection limit (3S/N) 12.0 mg · m^-3. The proposed method was applied to determination of n-butyl ether in air samples, giving results in consistency with those obtained by gas chromatography-mass spectrometry (GC-MS).
