Quartz crystal microbalances functionalized with citric acid-doped polyvinyl acetate nanofibers for ammonia sensing
Summary
Ammonia sensors made by covering QCMs with electrospun polyvinyl acetate nanofibres doped with oxalic, tartaric or citric acid, characterised by SEM, AFM and FTIR. The citric acid version performed best, with 2.95 Hz/ppm and a detection limit of 550 ppb, plus good selectivity, fast response and recovery and decent repeatability, at low cost.
Summary written by the openQCM team. The original abstract is on the publisher’s page.
