Electrospun PVA/g-C3N4/FeWO4 Nanofibers as a Multifunctional Platform for RB5 Dye Degradation, Antibacterial Activity and Zebrafish Embryo Biocompatibility
In this study, polyvinyl alcohol (PVA)/g-C3N4/FeWO4 nanofibres (PFG NFs) were synthesized via the electrospinning method, while bare materials were prepared using the hydrothermal method. These nanofibres were explored for their photocatalytic efficiency, antibacterial activity, and biocompatibility. The PFG NFs was characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM) with elemental mapping, and energy-dispersive X-ray spectroscopy (EDS). The photocatalytic performance was evaluated through the degradation of Reactive Black 5 (RB5) dye under solar light irradiation, achieving approximately 90% degradation in 100 min. Additionally, the antibacterial efficacy was assessed against Escherichia coli (E.coli) and Staphylococcus aureus (S.aureus), showing inhibition zones of 18 mm and 20 mm, respectively. Biocompatibility assessments using a zebrafish model revealed that the nanofibres exhibited good biocompatibility, with an applicable survival rate of 85%. These results indicate that the PFG NFs are promising candidates for environmental remediation, antibacterial applications, and biocompatibility-safe implementation.
期刊介绍：
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
