摘要
针对染料废水的处理问题,合成了Fe-ZIF-8 催化剂,采用X射线衍射、扫描电镜对其进行了结构表征,研究了其对亚甲基蓝模拟废水的光催化效果,考察了催化剂加入量、反应时间及pH值对降解效果的影响.实验结果表明:合成的催化剂对亚甲基蓝模拟废水有较好的光催化效果,在实验条件下,催化剂最佳用量为150 mg,pH值为9 时效果最好,反应进行3h降解率可达到98.53%以上.催化剂利用了金属有机骨架优异的物化性质,在降解染料废水方面具有良好的应用前景.
Abstract
A Fe-ZIF-8 catalyst was synthesized for the treatment of dye wastewater.Its structure was char-acterized by X-ray diffraction and scanning electron microscopy,and its photocatalytic effect on methylene blue simulated wastewater was studied.The effects of catalyst dosage,reaction time,and pH on the degra-dation efficiency were investigated.The experimental results show that the synthesized catalyst has a good photocatalytic effect on methylene blue simulated wastewater.Under experimental conditions,the optimal amount of catalyst is 150 mg,and the best effect is achieved at a pH of 9.After 3 hours of reaction,the degradation rate can reach above 98.53%.The catalyst utilizes the excellent physicochemical properties of metal-organic frameworks and has good application prospects for the degradation of dye wastewater.
