The elimination mefenamic acid (MA) as a pollutant from the aquatic environment using Hg lamp during a catalytic photodegradation process using supported ZnO–CuO onto clinoptilolite nanoparticles (NCP) was the aim of the study. Raw and supported clinoptilolite were characterized by FT-IR, XRD, DRS, TEM and SEM techniques. The changes of MA concentration determined by UV–vis double beam spectrophotometer at λ_max 285 nm and used for the calculation of its degradation extent. Better degradation efficiencies obtained for the supported the hybridized ZnO–CuO system onto NCP with respect to unsupported one and supported/unsupported ZnO and CuO. The degradation efficiencies are dependent to the experimental conditions and hence the parameters were optimized to reach the highest efficiencies.

负载型CuO-ZnO半导体对半真实样品甲芬那酸水溶液的光催化降解具有增强的光催化活性

本研究的目的是在负载的ZnO-CuO到斜发沸石纳米颗粒（NCP）上进行光催化降解过程中，使用汞灯从水生环境中消除作为污染物的甲芬那酸（MA）。通过FT-IR，XRD，DRS，TEM和SEM技术对原始斜发沸石和负载斜发沸石进行了表征。MA浓度的变化确定在通过UV-vis双光束分光光度计λ_最大285nm处，并且用于它的降解程度的计算。相对于无支撑的和支撑/无支撑的ZnO和CuO，在NCP上负载的ZnO-CuO杂化体系获得了更好的降解效率。降解效率取决于实验条件，因此对参数进行了优化以达到最高效率。
