As one of the harmful gases, hydrogen chloride (HCl) is produced by burning fuels that containing organochlorine compounds. The HCl gas is also frequently used in several workplaces that includes semiconductor manufacturing and polymer synthesis. Because of it’s harmful in human body such as corneal damage, skin rash, and respiratory disease, a number of HCl gas sensors based on polymer with basic groups have been developed. Especially, poly(acrylamide) derivatives based on quartz crystal microbalance (QCM) sensor have been used to detect HCl gas at ppm level. In this study, poly(N,N-dimethylamino ethyl methacrylate) was employed for QCM-based HCl gas sensor. Furthermore, the sensing characteristics (i.e., sensitivity, selectivity, and limit of detection) of the sensor were compared to that of poly(N,N-dimethylacrylamide) that commonly used to detect HCl gas. |
