Description of the data and file structure

Polymer Nanocomposites were synthesised using PolyVinylidene fluoride (PVDF) as host polymer and Carbon Quantum Dots(CQD)  as filler in different ratios by the electrospinning(S) method. Carbon Quantum Dots were prepared using polyvinylpyrrolidone (P) and Citric acid(C) as precursors. This is shortly referred to as SPVPC. Four samples were prepared. Based on proportions of added fillers, these are referred to as SPVPC-0, SPVPC-1, SPVPC-2, and SPVPC-3.

 The structure of the prepared polymer nanocomposite membranes was analysed using Fourier Transform InfraRed Spectroscopy(FTIR) and X-Ray Diffraction method(XRD). The morphology of the membranes was studied by Field Emission Scanning Electron Microscopy(SEM).

 As the objective of the experiment is to remove trace amounts of antibiotics from water, the membranes were added as adsorbents in water. Previously, a known concentration of antibiotic, Ciprofloxacin, was added to water.

 Adsorption, UV photodegradation and Scavenger experiments were performed, and concentrations of the antibiotics remaining after the experiment were studied by UV-Vis Spectrophotometer. The concentration of antibiotics in water after 30, 60, and 90 min was studied for all four membranes. The best of the four membranes was further exposed to UV for about 5 hours, and its degradation concentration was  analysed in various time intervals. The same experiment was repeated in the dark for the best membrane. One of the advantages of having polymer nanocomposites as adsorbents for the removal of antibiotics from water is their reusability, and hence their adsorption characteristics were studied up to 3 cycles for the best out of four membranes. Kinetics and Adsorption isotherm of the data were analysed using the equations given in the manuscript RSOS-251350 in section 2.7 with the data given in the folder RSOS-251350_ADSORPTION AND UV PHOTODEGRADATION STUDIES with the relevant sample name .

Porosity of the membranes were calculated using the formula given in the manuscript RSOS-251350 in section 2.6 and the data for three trials are given in the manuscript in Table 8.
