Abstract

In this study, graphene oxide (GO) was prepared by the Hummers' method from graphite material. The adsorption potential of GO-200 nm for the removal of Cr(vi) ions was investigated. Fourier transform infrared (FTIR) spectroscopy was used to analyze Cr(vi) before and after adsorption. The adsorption isotherm was fitted by the Langmuir model and the maximum adsorption capacity of the GO was 41.27 mg g at 25 °C. Thermodynamic parameters (Δ°), (Δ°), and (Δ°) were calculated and exhibited as +2.63 kJ mol K, +4.30 kJ mol K, and +5.56 kJ mol K at 30 mg L of Cr(vi) solution, respectively.

摘要

在本研究中，采用Hummers法由石墨材料制备氧化石墨烯（GO）。研究了200nm的GO对去除Cr(Ⅵ)离子的吸附潜力。利用傅里叶变换红外（FTIR）光谱对吸附前后的Cr(Ⅵ)进行分析。吸附等温线用Langmuir模型拟合，25℃时GO的最大吸附容量为41.27mg/g。在30mg/L的Cr(Ⅵ)溶液中，分别计算得到热力学参数（Δ°）、（Δ°）和（Δ°），其值分别为+2.63kJ/mol·K、+4.30kJ/mol·K和+5.56kJ/mol·K。
