In this study, the transport performance of acetaminophen (paracetamol), which is most commonly prescribed and used for humans and animals and whose wastes are known to have toxic effects on the environment and some living organisms, was investigated using zinc oxide (ZnO)-reinforced polymer membranes. In this study, nanoparticle-containing polymer membranes were prepared from cellulose triacetate in dichloromethane and ZnO nanoparticles were synthesized to impart adsorption properties to the membrane in a single step, enabling adsorption and filtration to improve the removal of low molecular weight micropollutants that are poorly retained by conventional polymer membranes and by enabling re-release. Our membrane was prepared by phase inversion method by doping with cellulose triacetate (CTA) solution. Parameters such as carrier concentration, mixing rate, transport time, acceptor and feed phase concentrations were studied to determine the optimal conditions for the transport experiments of paracetamol (PARA). The presence of acid in the acceptor phase converted the hydrophilic part of paracetamol, which allowed the transport of PARA. The calculated flux values for different PARA concentrations ranged from (0.64) × 10−8 to (1.8) × 10−8 mol/(cm2s). Under optimal conditions, a transport efficiency of 84% was obtained for PARA with a CTA/ZnO polymer membrane. The obtained membranes can be used in wastewater treatment, recovery of pharmacological products from pharmaceutical industry waste, re-evaluation of hospital waste, etc.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
