- Abstract
Detection of formaldehyde is extremely important considering its detrimental health hazards. It is extensively used as a potent preservative in different consumables like mushrooms, fish, etc. Although there are several methods to detect formaldehyde, developing a robust and accurate technique is always challenging. Here in, a reliable and accurate quartz crystal microbalance (QCM) based formaldehyde detection technique is presented where polyethylene glycol (PEG-400) is used as the prime sensing material. The developed sensor has achieved a wide linear detection range of (5–600 parts per million) with a sensitivity of 0.112 Hz/ppm and a linear correlation coefficient ( R 2) of 0.946. The lowest detection limit of Formaldehyde was 3.95 ppm. The performance of the developed sensor was assessed for different samples of mushrooms which yielded about 99.61% accuracy in the predicted concentrations of formaldehyde using PCR analysis.
