Catalyst for removing bisphenol A in water by activating persulfate as well as preparation method and application of catalyst

The invention discloses a catalyst for removing bisphenol A in water by activating persulfate as well as a preparation method and application of the catalyst. The catalyst prepared by the invention is cobaltosic oxide which is rich in hydroxyl radicals on the surface and is obtained by reacting cobalt nitrate hexahydrate with hexadecyl trimethyl ammonium bromide. The catalyst can effectively activate persulfate to remove a pollutant bisphenol A in wastewater. The catalyst disclosed by the invention is simple in composition, excellent in performance, easy to prepare and easy for large-scale production, and has important significance in practical application of a persulfate advanced oxidation process in the field of environmental pollutant treatment. 本发明公开了一种通过活化过硫酸盐除去水中双酚A的催化剂及其制备方法和应用，本发明制备的催化剂为六水合硝酸钴与十六烷基三甲基溴化铵反应得到表面富含氢氧根的四氧化三钴。该催化剂能有效活化过硫酸盐去除废水中的污染物双酚A。本发明所述催化剂组成简单、性能优异、易于制备，容易规模化生产，这对于过硫酸盐高级氧化工艺在环境污染物治理领域中的实际应用具有重要意义。
