PERFORMANCE OF Bi2WO6@MXenes-NS ACTIVATED PERMONOSULFATE IN DEGRADING BISPHENOL A

  • 摘要: 为解决水环境中内分泌干扰物的去除难题,采用水热法合成Bi2WO6@MXenes-NS(BM-NS)复合催化剂,通过活化过单硫酸盐(PMS)降解双酚A (BPA)。利用SEM、TEM及XRD对所制备催化剂的形貌和晶体结构进行表征,考察了不同催化剂体系、PMS浓度,溶液pH和共存离子等因素对BPA降解性能的影响。结果表明:当MXenes-NS添加量(质量分数)为0.5%,催化剂浓度为1 g/L,PMS浓度为0.3 g/L,溶液pH为3.03时,BM-NS/PMS体系具有较强的BPA降解性能,120 min内去除率达到85.3%。溶液中无机阴离子对BPA去除率的影响顺序为Cl-2PO-42-4-3≈NO-3。催化剂经过4次循环实验后,BPA去除率仍保持在70.1%。自由基猝灭实验结果表明,SO-4·是主要的活性自由基。结合LC-MS,提出了BPA可能的降解途径。研究表明,制备的BM-NS催化剂在活化PMS降解BPA方面具有良好的应用前景。
