通过简单的水热法和KOH活化法制备了一种吸附性能和催化性能优良的材料Co-CNTs-KOH，并对其进行表征分析；考察了Co-CNTs-KOH投加量、BPA初始质量浓度、PMS投加量、pH和离子强度等因素对降解BPA效果的影响。结果表明，所制备的催化剂Co-CNTs-KOH为表面粗糙、疏松多孔的不规则形状，具有较高的结晶度和密集分布的介孔结构；在催化剂质量浓度为20 mg/L、BPA初始质量浓度为20 mg/L、PMS浓度为0.5 mmol/L、弱酸条件下，BPA的降解效果最佳，降解率高达93.5%；通过自由基猝灭反应得出结论，SO₄^-·和OH·自由基是该体系主要的活性氧化物质。

Co-CNTs-KOH, a material with good adsorption and catalytic properties, is prepared by simple hydrothermal method and KOH activation method, and characterized and analyzed.The effects of Co-CNTs-KOH dosage, bisphenol A initial concentration, PMS dosage, pH and ionic strength on the degradation effect of bisphenol A are investigated.The results show that the prepared Co-CNTs-KOH has a rough surface, loose and porous irregular shape, high crystallinity and dense mesoporous structure.It is found that the degradation effect of bisphenol A reaches the best with a degradation rate as high as 93.5% when the catalyst dosage is 20 mg·L^-1, the initial concentration of bisphenol A is 20 mg·L^-1, the concentration of PMS is 0.5 mM, and under weak acid conditions.Through free radical quenching reaction, it is discovered that SO₄^-· and OH· radicals are the main active oxidizing substances in the system.
