一种类芬顿催化剂的制备及其降解废水的应用

Preparation of A Kind of Fenton Catalyst and Its Application in Degrading Wastewater

采用固相法将一定质量比的三聚氰胺、氯化锂、氯化钾、三氯化铁混合均匀,装入坩埚中放置于马弗炉中加热3~7 h之后,降至室温,用去离子水洗涤后放置于烘箱中干燥,得到一种类芬顿催化剂。采取氮气吸附,红外光谱,XPS,紫外漫反射等手段进行表征所制备的催化剂,并在双氧水作用下,对含有盐酸四环素的有机废水的降解性能优良,而且在pH值为3~11下都有较好的效果,降解率可达98%~99.5%。

Solid phase method was used to mix melamine,lithium chloride,potassium chloride and ferric chloride of a certain mass ratio evenly,putting them into a crucible and putting them into a muffin furnace for heating for 3~7 h.After that,they were heated to room temperature,washed with deionized water and dried in an oven to obtain a kind of fenton catalyst.The catalyst prepared by nitrogen adsorption,infrared spectroscopy,XPS,UV diffusion and other methods was characterized.Under the action of hydrogen peroxide,the degradation performance of organic wastewater containing tetracycline hydrochloride was excellent,and the degradation rate was up to 98%~99.5%at pH value of 3~11.
