摘要
采用一步式水热合成法制备铜铁掺杂BiOCl(Cu-Fe/BiOCl)可见光催化剂,采用XRD和SEM对催化剂进行表征。研究可见光下对Cu-Fe/BiOCl活化过硫酸钾(PS)去除罗丹明B(RhB)的活化作用以及其反应机理。选取溶液初始pH值、Cu-Fe/BiOCl投加量、过硫酸盐投加量和RhB初始浓度等四个参数,研究在可见光/Cu-Fe/BiOCl/PS体系下RhB的脱色效率。结果表明,在催化剂投加量为0.5gL-1、过硫酸盐投加量为1mM时为最佳处理条件,脱色效率达到100%。
Cu-Fe/BiOCl was successfully synthesized by one-step hydrothermal method, and further characterization by XRD and SEM.This paper studied the visible radiation activated potassium persulfate for Rhodamine B (RhB) degradation enhancement effect and its reaction mechanism.The effects of experiment parameters, such as solution pH value, Cu-Fe/BiOCl dosage, persulfate dosage and initial RhB concentration, on the degradation of RhB in Vis/Cu- Fe/BiOCl/PS system were studied.The results showed that the optimum treatment conditions were as follows: the catalyst dosage was 0.5 g L-1 and the persulfate concentration was 1 mM that can make the degradation efficiency reach to 100 % in 60 minutes.
