An (Fe, Ag) co-doped ZnO nanostructure was synthesized by a simple chemical co-precipitation method and used for the degradation of dibutyl phthalate (DBP) in aqueous solution under visible light-emitting diode (LED) irradiation. (Fe, Ag) co-doped ZnO nanorods were characterized by powder X-ray diffraction, Fourier transform infrared spectroscopy, UV-VIS diffuse reflectance spectroscopy, elemental mapping, Field emission scanning electron microscopy, transmission electron microscope and Brunauer-Emmett-Teller surface area analysis. A Central Composite Design was used to optimize the reaction parameters for the removal of DBP by the (Fe, Ag) co-doped ZnO nanorods. The four main reaction parameters optimized in this study were the following: pH, time of radiation, concentration of the nanorods and initial DBP concentration. The interaction between the four parameters was studied and modeled using the Design Expert 10 software. A maximum reduction of 95% of DBP was achieved at a pH of 3, a photocatalyst concentration of 150 mg L and a DBP initial DBP concentration of 15 mg L. The results showed that the (Fe, Ag) co-doped ZnO nanorods under low power LED irradiation can be used as an effective photocatalyst for the removal of DBP from aqueous solutions.
通过简单的化学共沉淀法合成了一种（铁，银）共掺杂的氧化锌纳米结构，并将其用于在可见光发光二极管（LED）照射下对水溶液中的邻苯二甲酸二丁酯（DBP）进行降解。通过粉末X射线衍射、傅里叶变换红外光谱、紫外-可见漫反射光谱、元素映射、场发射扫描电子显微镜、透射电子显微镜和布鲁诺尔-埃米特-泰勒表面积分析对（铁，银）共掺杂的氧化锌纳米棒进行了表征。采用中心复合设计优化了（铁，银）共掺杂氧化锌纳米棒去除DBP的反应参数。本研究中优化的四个主要反应参数如下：pH值、辐射时间、纳米棒浓度和DBP初始浓度。使用Design Expert 10软件研究并模拟了这四个参数之间的相互作用。在pH值为3、光催化剂浓度为150 mg L且DBP初始浓度为15 mg L时，DBP的最大去除率达到了95%。结果表明，在低功率LED照射下，（铁，银）共掺杂的氧化锌纳米棒可作为从水溶液中去除DBP的有效光催化剂。
