Novel polyvinylidene fluoride-carbon quantum dot polymer nanocomposite membrane for removal of antibiotics from water

Abstract Carbon quantum dot (CQD)-based nanocomposites are widely used as fluorescent sensors for the detection of antibiotics in water; however, the use of CQDs for water remediation is largely unexplored. In this study, a novel polyvinylidene fluoride (PVDF) membrane modified with CQDs was developed by electrospinning to remove ciprofloxacin from water. A hydrothermal method was used to prepare CQD with polyvinylpyrrolidone (PVP) as a precursor. Fourier transform infrared spectroscopy (FTIR) a
