| 摘 要： | 采用水热合成法在pH12的条件下合成圆片状Bi3.84W0.16O6.24催化剂.通过XRD、FESEM、TEM、UV-vis漫反射等表征分析Bi3.84W0.16O6.24的物相、形貌和吸光性能.以双酚A(BPA)为目标污染物,研究了Bi3.84W0.16O6.24在模拟太阳光辐射下的光催化反应活性.设计L18(37)正交试验研究了BPA初始浓度、催化剂投入量、反应溶液pH值以及光催化反应时间对Bi3.84W0.16O6.24光催化降解BPA的影响.正交试验的极差和方差分析结果表明,BPA初始浓度和反应时间影响非常显著,催化剂用量影响显著,反应溶液pH值影响不显著,初始浓度和催化剂量的交互作用很小.在BPA初始浓度为20mg/L、催化剂量2g/L、反应溶液pH7、反应时间为90min的条件下Bi3.84W0.16O6.24对BPA去除率达99.5%,TOC去除率为86.0%,BPA的降解符合一级反应动力学.
