Molecularly imprinted polymers (MIPs) have been received considerable attention as useful smart materials for detecting volatile organic compound (VOC) gases due to their remarkable recognition properties for the parent templates. In this work, quartz crystal microbalance (QCM) array sensors coated with different sensing materials were fabricated to effectively and simultaneously detect multiple toxic species. For this purpose, the molecular imprinting technique was particularly employed for improving the selectivity for VOCs such as benzene and isopropyl methyl ketone. The responses measured by the sensor systems were systematically analyzed and evaluated by means of several adsorption equilibrium isotherm models such as extended Langmuir, loading ratio correlation (LRC), and ideal adsorbed solution theory (IAST). |
