Abstract:

以氯化铁和氧化铁为原料,采用化学气相迁移法在密封条件下制备了氯氧化铁(FeOCl)催化剂,通过扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X射线衍射光谱(XRD)、X光电子能谱(XPS)等分析手段对催化剂进行表征,研究了罗丹明B(RhB)初始浓度、H_2O_2添加量、催化剂用量、初始pH值等对RhB脱色率的影响.结果表明:在催化剂用量为0.5 g·L~(-1)、RhB初始浓度为100 mg·L~(-1)、H_2O_2浓度为20 mmol·L~(-1)、初始pH值为4.5时,可见光下经过15 min的催化反应,RhB脱色率达到99%以上;初始pH值为7.0时,经过40 min,RhB的脱色率也可达到95.5%;添加一定量的H_2O_2,能够促进羟基自由基(·OH)生成,提高脱色效率;催化剂稳定性良好,3次重复催化实验后,RhB的脱色率无明显降低
