Abstract

Graphene oxide (GO) nanosheets were functionalized with Schiff base and reduced Schiff base. Covalent and non-covalent functionalized GO nanostructures have been tested for the removal of pesticides with different chemical structures and properties (e.g., Epoxiconazole, Dimethomorph, Cyprodinil, Chlorothalonil, Acetochlor, Trifluralin) from aqueous solutions. The structure and morphology characteristics of the prepared structures were analyzed using techniques such as solid-state nuclear magnetic resonance (SSNMR), Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). Results of the experiments showed that, although the non-covalent functionalization did not affect the adsorption properties of GO much, the covalent functionalization increased the adsorption capacity of GO against the mentioned pesticides.

摘要

氧化石墨烯（GO）纳米片用席夫碱和还原席夫碱进行了功能化处理。已对共价和非共价功能化的GO纳米结构从水溶液中去除具有不同化学结构和性质的农药（例如，环氧唑菌唑、烯酰吗啉、嘧菌环胺、百菌清、乙草胺、氟乐灵）进行了测试。使用固态核磁共振（SSNMR）、傅里叶变换红外（FTIR）光谱、X射线衍射（XRD）、热重分析（TGA）、扫描电子显微镜（SEM）和透射电子显微镜（TEM）等技术对制备结构的结构和形态特征进行了分析。实验结果表明，虽然非共价功能化对GO的吸附性能影响不大，但共价功能化提高了GO对上述农药的吸附能力。
