摘要：Organic pollutant gases can cause severe damage to both materials and people and have received much attention as a problem in the indoor environment. In this paper, 1-butyl-3-methylimidazolium chloride (C(4)mimCl) was employed as sensing material coated on quartz crystal microbalance (QCM) for the detection of organic vapors. The experimental results indicated that the C(4)mimCl/QCM sensor showed fast response, excellent sensitivity and good reproducibility towards organic acids. There was a good linear relationship between the frequency response and the testing concentration of these organic acid vapors. The results also indicated that C(4)mimCl/QCM sensor could be a good candidate for the real-time detection of organic acid vapors.
