以乌龙茶提取物为原料合成铁基纳米颗粒。通过扫描电镜（SEM）、x射线能谱（EDS）、x射线衍射（XRD）、紫外可见（UV-vis）和傅里叶变换红外光谱（FTIR）对其形貌、结构和尺寸进行了表征。FeNP的形成主要是直径在40到50纳米之间的球形颗粒。OT-FeNP对孔雀石绿（MG）的降解动力学符合准一级反应，去除率为75.5% （50 MG /L）。这表明OT-FeNP具有作为一种绿色纳米材料用于环境修复的潜力。(C) 2013 Elsevier B.V.版权所有
Iron-based nanoparticles (OT-FeNP) were synthesized using oolong tea extracts. Their morphology, structure and size were confirmed by scanning electron microscopy (SEM), X-ray energy-dispersive spectroscopy (EDS), X-ray diffraction (XRD), UV-visible (UV-vis) and Fourier Transform Infrared spectroscopy (FTIR). Formation of FeNP results in mostly spherical particles with diameters ranging from 40 to 50 nm. Degradation of malachite green (MG) using OT-FeNP demonstrated that kinetics fitted well to the pseudo first-order reaction by removing 75.5% of MG (50 mg/L). This indicated that OT-FeNP has the potential to serve as a green nanomaterial for environmental remediation. (C) 2013 Elsevier B.V. All rights reserved.
