摘要

本研究介绍了一种高效环保的方法，利用合成的氧化锌纳米颗粒降解药物污染物。利用荧光光谱、紫外-可见光谱、红外光谱、粒度分析、Zeta电位、PXRD、FE-SEM和EDAX技术对纳米颗粒的结构和光学性质进行了广泛的表征。利用氧化锌和Fenton试剂在较宽的pH范围（2.5、7.0和10.5）和不同的光源下，成功地实现了对乙酰氨基酚（PARA）和双氯芬酸（DCF）的光催化降解。在所有测试的光源下，较低pH值（pH = 2.5）比较高pH值（pH = 7.0和10.5）的降解效率更高。值得注意的是，在pH为2.5的UV254下，ZnO在45分钟内完全降解，优于其他测试条件。本研究强调了ZnO光催化剂及其功能化在有效减轻药物污染物对环境影响方面的潜力。

Sustainable Solutions: ZnO Nanoparticles for Enhanced Photocatalytic Treatment of Paracetamol and Diclofenac

This study introduces an efficient and environmentally friendly approach by utilizing synthesized ZnO nanoparticles to degrade pharmaceutical contaminants. The structural and optical properties of the nanoparticles were extensively characterized using Fluorescence spectrometry, UV–VIS spectroscopy, FTIR spectroscopy, particle size analysis, Zeta potential, PXRD, FE-SEM, and EDAX techniques. The photocatalytic degradation of paracetamol (PARA) and diclofenac (DCF) was successfully achieved using ZnO in combination with Fenton’s reagent across a wide pH range (2.5, 7.0, and 10.5) and various light sources. Enhanced degradation efficiency was observed at lower pH levels (pH = 2.5) than at higher pH values (pH = 7.0 and 10.5) under all light sources tested. Notably, ZnO achieved complete degradation within 45 min under UV254 exposure at pH 2.5, outperforming other conditions tested. This research highlights the potential of ZnO photocatalysts and their functionalization to effectively mitigate the environmental impact of pharmaceutical pollutants.

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.
