摘要

采用紫外发光二极管联合次氯酸钠高级氧化工艺(UV/Cl

)对β-受体阻滞剂美托洛尔(Metoprolol

MTP)的降解进行研究

考察MTP降解的影响因素。结果表明

UV/Cl

对MTP的去除率可达95.2%且具有协同作用

反应符合准一级反应动力学

降解速率常数随辐照度、溶液pH增大而增大

随氯剂量的增加先增大后减少

随MTP初始质量浓度、抑制剂叔丁醇浓度的增加而减少。

Abstract

Using UV-LED / Cl

Advanced Oxidation Process to study the degradation of metoprolol (MTP)

one of the β-blocker

the effects of light intensity

chlorine dosage

TBA and other factors on the degradation of MTP are investigated. Studies have shown that UV-LED / Cl

can effectively remove MTP by synergy. The MTP degradation during UV-LED / Cl

treatment satisfies pseudo-first-order kinetics

and the pseudo-first-order rate constants of MTP (

obs

) increases with the UV-LED light intensity and the pH of the solution. With the increase of the chlorine dose

the

obs

of MTP increases first and then decreases. The

obs

of MTP decreases with the increase of the initial concentration of MTP and TBA

and TBA has a strong inhibitory effect on MTP degradatio

n during UV-LED / Cl

treatment.
