Tổng hợp vật liệu composite Fe-BTC ứng dụng xử lý Cr(VI) trong môi trường nước

The escalating challenge of industrial wastewater pollution, particularly from heavy metal ions such as hexavalent chromium (Cr(VI)), poses a significant threat to aquatic ecosystems and human health. Conventional water treatment methods often fall short in terms of efficiency, cost-effectiveness, or sustainability. In this context, the development of advanced functional materials for effective pollutant remediation has become paramount. This study addresses this critical environmental issue by focusing on the synthesis and application of a novel Fe-BTC composite material. We aim to explore its potential as an efficient photocatalyst for Cr(VI) removal in aqueous environments, thereby contributing to sustainable water treatment technologies and mitigating the impact of industrial discharges.

This academic work presents a comprehensive investigation into the synthesis and photocatalytic efficiency of a novel Fe-BTC composite material for the remediation of hexavalent chromium (Cr(VI)) in aqueous solutions. Addressing the pressing environmental concern of heavy metal pollution from industrial effluents, the study employs a hydrothermal crystallization method at 120°C for 12 hours to successfully synthesize the Fe-BTC composite. The material's structural, morphological, and optical properties were thoroughly characterized using advanced techniques such as X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Infrared Spectroscopy (IR), and UV-Vis Diffuse Reflectance Spectroscopy (DRS). Experimental results revealed that the synthesized Fe-BTC composite consists of spherical crystals possessing a high specific surface area, which is crucial for enhanced catalytic activity. The Cr(VI) treatment efficacy was systematically evaluated under varying parameters, including pH levels, initial Cr(VI) concentrations, and catalyst dosage. Notably, the composite demonstrated significant Cr(VI) removal efficiency, achieving up to 92.72% at an initial Cr(VI) concentration of 10 ppm under UV light irradiation and optimal pH 7. An optimal catalyst dosage of 30mg/100ml was identified to balance efficiency and material usage. These findings highlight the promising potential of the Fe-BTC composite as an effective, sustainable, and economically viable photocatalyst for tackling Cr(VI) pollution, offering valuable implications for advanced water treatment processes and environmental protection.
