摘要
医院废水是药物污染物的主要来源，尤其是四环素等抗生素。四环素经常作为污染物出现在水体中，这主要是由于其通过人类和动物排泄物的不当处置和排泄造成的。这种废水对环境和健康构成严重威胁。为了解决这一令人担忧的问题，我们合成了一种新型复合材料 M 型六价铁铅/氮化碳（PbFe12O19/g-C3N4）。六价铁铅与石墨化-C3N4的结合效应旨在增强四环素（TC）的降解。利用 X 射线衍射光谱（XRD）、扫描电子显微镜（SEM）、傅立叶变换红外光谱（FTIR）和紫外-可见光谱对合成的复合材料进行了表征。在阳光照射下，对样品的光催化输出进行了评估。结果表明，与单个成分相比，仅在 60 分钟内四环素的去除率就高达 90%。这项工作凸显了 PbFe12O19/g-C3N4 复合材料作为有效光催化剂处理制药污染物（尤其是废水中的四环素）的潜力。
Efficient tetracycline removal from hospital wastewater using visible light active M-type lead hexaferrite/g-C3N4 composites
The hospital wastewater is major contributor to pharmaceutical contaminants, particularly antibiotic like tetracycline. Tetracycline is often found as a pollutant in water bodies, primarily due to its improper disposal and excretion through human and animal waste. This wastewater poses serious environmental and health risks. We synthesized a novel composite material M type lead hexaferrites/g-carbon nitride (PbFe12O19/g-C3N4) to address this alarming issue. The combine effect of lead hexaferrite with graphitic-C3N4, aiming to enhance the degradation of tetracycline (TC). The characterization of the synthesized composite was conducted using X-ray diffraction spectroscopy (XRD), Scanning electron microscope (SEM), Fourier transform infrared radiation spectroscopy (FTIR) and UV-Visible spectroscopy. The photocatalytic output of the samples was evaluated under sunlight irradiation. The results demonstrated superior removal efficiency of tetracycline up to 90% in only 60 min compared to individual components. This work highlights the potential of PbFe12O19/g-C3N4 composites as effective photocatalysts for treating pharmaceutical contaminants especially tetracycline in wastewater.
期刊介绍：
The primary objective of the Journal of Sol-Gel Science and Technology (JSST), the official journal of the International Sol-Gel Society, is to provide an international forum for the dissemination of scientific, technological, and general knowledge about materials processed by chemical nanotechnologies known as the "sol-gel" process. The materials of interest include gels, gel-derived glasses, ceramics in form of nano- and micro-powders, bulk, fibres, thin films and coatings as well as more recent materials such as hybrid organic-inorganic materials and composites. Such materials exhibit a wide range of optical, electronic, magnetic, chemical, environmental, and biomedical properties and functionalities. Methods for producing sol-gel-derived materials and the industrial uses of these materials are also of great interest.
