Degradation of Rhodamine B by Carbon Nitride Activated Sodium Persulfate under Visible Light Irradiation

  • 摘要: 本文以尿素为原材料,高温聚合法制备了石墨相氮化碳(g-C3N4)纳米片催化剂,采用X射线衍射(XRD)、紫外可见漫发射(DRS)等对g-C3N4进行表征,研究了可见光下g-C3N4活化过硫酸钠对罗丹明-B的效果,并对降解过程中的影响因素如g-C3N4的投入量、过硫酸钠的投入量进行了考察. 结果表明:g-C3N4在可见光下协同过硫酸钠降解罗丹明-B的效果最佳,反应30分钟后,降解率达到91.67%. 罗丹明-B的降解效率随着g-C3N4和过硫酸钠投加量的增加而提高. 对反应过程中过硫酸钠浓度的滴定结果表明:g-C3N4在可见光下对过硫酸钠有一定的活化效果. 经过四次循环降解实验,g-C3N4催化剂仍然具有较好的活性.
