Abstract

This study investigates the use of zinc oxide (ZnO) as a semiconductor photocatalyst, applied to Tamarix articulata stems (TA), for the photocatalytic oxidation of clofibric acid (CA). The microstructural properties of the ZnO-impregnated TA samples were examined using scanning electron microscopy (SEM–EDX). Chemical characterization was performed through Fourier Transform Infrared Spectroscopy (FT-IR). The pH dependence of CA degradation was found to be optimal within the pH range of 7 to 9. The study revealed that the maximum degradation efficiency of CA reached 67% at an initial concentration of 2.5 mg/L and 30% at 10 mg/L. The catalyst loading was optimized at 1 g/L. The degradation kinetics adhered to a pseudo-first-order model, with the rate constant being influenced by the catalyst concentration.

氧化锌浸渍柽柳茎增强纤维酸光催化降解

本文研究了氧化锌（ZnO）作为半导体光催化剂，应用于柽柳茎（TA）的光催化氧化纤维酸（CA）。利用扫描电子显微镜（SEM-EDX）研究了zno浸渍TA样品的显微组织性能。通过傅里叶变换红外光谱（FT-IR）进行了化学表征。在7 ~ 9的pH范围内，CA降解的pH依赖性最佳。研究表明，CA在初始浓度为2.5 mg/L时的最大降解效率为67%，在初始浓度为10 mg/L时达到30%。催化剂的负载优化为1 g/L。降解动力学服从准一级模型，速率常数受催化剂浓度的影响。
