Noticing the Phytoextract Mediated Zinc Oxide Nanoparticles Synthesis, Characterization, and Antimicrobial, Antioxidant & Photocatalytic Applications
The present work successfully fabricates straightforward, eco-friendly, and economical zinc oxide nanoparticles (ZnO NPs) using Alpinia galanga rhizome extract. Characterization via Ultraviolet–visible (UV–vis) spectrophotometry revealed a peak at 374 nm. X-ray diffraction (XRD) analysis revealed a pristine hexagonal wurtzite structure of NPs with an average crystallite size of 49.86 nm. Field emission scanning electron microscopy (FESEM) confirmed cubic-shaped nanoparticles with an average size of 68.86 ± 9.67 nm. Energy dispersive X-ray (EDX) showed a sharp peak for Zinc. Fourier transform infrared (FTIR) identified surface functional groups. This means the surface charge of NPs was -21 ± 0.8 mV. The antibacterial effectiveness of ZnO NPs exhibited better susceptibility against Gram-negative Pseudomonas aeruginosa (MIC 6.25 µg/mL) compared to Gram-positive Bacillus subtilis (MIC 12.5 µg/mL). Additionally, ZnO NPs displayed robust antioxidant activity, scavenging 80% of DPPH with an IC50 of 114.2 µg/mL. Furthermore, ZnO NPs degraded 94% of Methylene blue (MB), as well as 76% and 72% of Congo red (CR) at 50 mg/100 mL and 100 mg/100 mL ZnO NPs loaded concentration, following pseudo-first-order kinetics and showed stability over three cycles. Thus, the environmentally benign production and nontoxicity of ZnO NPs derived from A. galanga can be employed as candidates for antibacterial, antioxidant agents, and industrial effluent treatment.
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.
