Abstract

In this study, zinc oxide nanorods, co-doped with iron and silver, were synthesized in a co-precipitation method. Its properties were determined using X-ray diffraction (XRD), Transmission electron microscopy (TEM), Field Emission Scanning Electron Microscopy (FE-SEM), Brunauer-Emmett-Teller (BET), Dynamic light scattering (DLS) and X-ray photoelectron spectroscopy (XPS) analysis. The results of FE-SEM and TEM showed that zinc oxide nanoparticles synthesized and co-doped with iron and silver were formed as separate nanorods. Also, the average values of DBP and DEHP amount of phthalates in the leachate from the landfill site of Aradkouh were obtained 52.5 and 94.69 mg/L, respectively. The highest removal efficiency in real samples for phthalates was found to be 52%. The highest removal efficiency of TOC were was 61%. The synthesized nanostructure could have proper efficiency in removal of phthalates from water sources under the visible light of LED lamp.

摘要

在这项研究中,氧化锌纳米棒,与铁和银共掺杂，以共沉淀法合成。用X射线衍射(XRD)测定其性能,透射电子显微镜(TEM),场发射扫描电子显微镜(FE-SEM),Brunauer-Emmett-Teller（BET），动态光散射(DLS)和X射线光电子能谱(XPS)分析。FE-SEM和TEM结果表明，合成并与铁和银共掺杂的氧化锌纳米颗粒形成为单独的纳米棒。此外，Aradkouh垃圾填埋场渗滤液中邻苯二甲酸盐的DBP和DEHP含量的平均值分别为52.5和94.69mg/L，分别。发现实际样品中邻苯二甲酸酯的最高去除效率为52%。TOC的最高去除效率为61%。合成的纳米结构在LED灯的可见光下从水源中去除邻苯二甲酸酯具有适当的效率。
