基于铈元素设计的金属有机框架催化剂用以水体中抗生素的去除

Cerium-Based Met-al-Organic Framework Catalysts for the Removal of Antibiotics from Water

本文设计了一种基于铈元素开发的金属有机框架作为催化剂,用以活化过一硫酸盐这一高级氧化工艺,以达到四环素的去除。通过选择不同配体优化材料的稳定性和催化能力,并且对制备成功的催化剂Ce-MOF-3进行了红外光谱、扫描电镜、透射电镜、X射线衍射等多种方法的材料表征。并且用紫外吸收光谱验证了其四环素的去除率,针对浓度为20 mg/L的四环素溶液,其去除率在30分钟内高达69.67%。

be used as a catalyst for the activation of peroxynitrite, an advanced oxidation process for tetracycline removal. The stability and catalytic ability of the material were optimized by choosing different ligands, and the prepared catalyst Ce-MOF-3 was characterized by various methods such as infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and X-ray diffraction. And the removal rate of tetracycline was verified by ultraviolet absorption spectroscopy, which was as high as 69.67% in 30 min for a tetracycline solution with a concentration of 20 mg/L.
