摘要

本文采用氧化石墨烯与氯金酸直接反应制备了氧化石墨烯-金纳米颗粒(GO- aunps)纳米复合吸附剂，用于去除水溶液中的阿莫西林。利用红外光谱对纳米复合材料(GO-AuNPs)进行表征。通过多次吸附实验，考察了接触时间、溶液pH、阿莫西林初始浓度、温度等参数对吸附行为的影响。吸附动力学用拟二级速率模型描述得很好。

Kinetics adsorption of Amoxicillin from aqueous solution by Graphen Oxide- Gold nanoparticles (GO-AuNPs) nanocomposite as novel adsorbent

A BSTR AC T: In this study, Graphene Oxide- Gold nanoparticles (GO-AuNPs) nanocomposite as novel adsorbent was synthesized by direct reaction between GO and chloroauric acid for removal of amoxicillin from aqueous solution. Nanocomposite (GO-AuNPs) was characteristic by FT-IR spectroscopy. The changes of parameters such as contact time, pH of solution, initial amoxicillin concentration and temperature were measured and investigated by several adsorption experiments various factors affecting the uptake behavior. The adsorption kinetics well described by a pseudo-secondorder rate model.
