| 摘 要： | 目的建立一种气相色谱测定空气中氰化物的方法。方法采用衍生化顶空进样技术，用气相色谱进行定量测定。结果该方法的最低检出限为0．028μg，若取样3L，则最低检出浓度为0．009mg／m^3，线性范围0．1-6．0μg。相关系数r=0．9997，回归方程Y=71．5 X＋9．68。结论该方法操作简便，抗干扰能力强，线性范围宽，检测限低，适用空气中氰化物的测定，是一个较为理想的检测方法。

| Abstract: | Objective] To establish gas chromatography for the determination of cyanide in air. Methods ] Derivatives of headspace sampling techniques were adopted to perform quantitative measurement of the sample by gas chromatography. Results ] The minimal detection limit of the method is 0. 028 μg. If sampling 3 L, the minimal detectable concentration is 0.009 mg/m^3, the linear range is 0.1-60μg. The correlation coefficient is r =0. 9997. The regression equation is Y = 71.5 X ＋9.68. Conclusion] The method is easy-to-handle and has strong interference capability, wide linear range and low detection limit. It is an ideal detection method for detection of cyanide in air. |
