Comparative Degradation Kinetics Study of Polyamide Thin Films in Aqueous Solutions of Chlorine and Peracetic Acid Using Quartz Crystal Microbalance

Abstract: Polyamide thin film composite membranes are widely used in water reclamation. Peracetic acid (PAA) is an emerging wastewater disinfectant with a potential for membrane cleaning and disinfection; however, its interaction with polyamide remains poorly understood. This study employs quartz crystal microbalance with dissipation (QCM-D) to determine the PAAinduced degradation kinetics of polyamide thin films, in comparison with the conventional disinfectant-free chlorine (HOCl). Polyamide films showed a sorption ph… Show more

“…Additionally, by simultaneously measuring energy dissipation, it provides valuable information about the viscoelasticity of the adsorbed layer. QCM-D can also be used to monitor the cleaning dynamics, as long as the shear wave is still present in the adsorbed film, and this technique has been applied in several recent studies. , However, despite its compatibility with QCM-D, the removal dynamics in the electronics industry, which demands high-precision cleanliness, is still unclear. This emphasizes the potential of QCM-D as an analysis platform for evaluating new cleaning methods using interfacial technology.…”

“…A quartz crystal microbalance (QCM) is highly precise in measurements of the weight loss of a thin polymer film evenly deposited onto an electrode. 11,12 Highperformance liquid chromatography, gel permeation chromatography, and gel electrophoresis are typical quantitative techniques to quantitate and identify the chemical structure of reaction products dissolved in aqueous media. [13][14][15] The precision improves drastically with these methods, but they still require sampling and are applicable only to macroscopic substances.…”
