中文摘要：

采用离子液体氯化1-己基-3-甲基咪唑（C6 mimCl）作为石英晶体微天平（QCM）的涂敷材料制成C6 mimCI／OCM传感器，对以甲酸和乙酸为代表的有机酸性气体进行监测。研究结果表明，C6 mimCI／OCM传感器对甲酸和乙酸气体均具有响应速率快、灵敏度高和重现性好等特点，该传感器的频率响应信号与被测有机酸性气体浓度呈良好的线性关系，可用于污染物浓度不断升高的博物馆环境的实时在线监测。

英文摘要：

Organic acid gases with strong corrosive will cause severe damage to a variety of materials, especially to the cultural relics which have great historical value. 1-Hexyl-3-methylimidazolium chloride （C6mimC1） was employed as sensing material coated on quartz crystal microbalance （QCM） for the detection of organic vapors （formic acid and acetic acid）. Results indicated that the C6mimC1/QCM sensor showed fast response, excellent sensitivity and good reproducibility towards organic acids. In addition, there was a good linear relationship between the frequency response and the testing concentrations of these organic acid vapors. C6mimC1/QCM sensor could be a good candidate for the real-time detection of organic acid vapors in antique conservation environment.
