摘要

为了探究钨酸亚铁作为催化剂的超声催化性能，通过水热法成功合成了半导体纳米材料钨酸亚铁，分别使用XRD、SEM对制得的钨酸亚铁催化剂进行测试表征，并使用UV－Vis分光光度法研究了钨酸亚铁催化超声降解偶氮荧光桃红，考察催化剂的加入量、溶液pH和超声时间对其超声催化降解性能的影响，同时还探究了催化剂的可重复利用性和选择性.实验结果表明：钨酸亚铁具有较好的催化活性，在处理有机染料废水方面有良好的应用前景.

Abstract:

In order to explore the ultrasonic catalytic properties of ferrotungsten subcatalyst,the semiconductor nanomaterials ferrous tungsten catalyst was successfully synthesized by hydrothermal method.XRD and SEM were used to test and characterize the prepared ferrous tungstate catalyst,and UV-Vis spectrophotometry was used to studythe ultrasound catalytic degradation of azo fluorescent peach red by ferrous tungstate.The influence of catalyst addition,solution pH and ultrasonic time on the ultrasonic catalytic degradation performance of the catalyst were investigated.The repeability and selectivity of the catalyst are also explored.The experimental results show that iron tungsten acid has good catalytic activity and good application prospect in treating organic dye wastewater.
