摘要/Abstract

摘要： 以氧化石墨烯(GO)为基体,黄原胶(XG)为交联剂,磷酸(P)为修饰剂制备了磷酸功能化黄原胶/氧化石墨烯凝胶(P-XG/GO),并应用于铀的选择性吸附。扫描电子显微镜(SEM)、X射线衍射(XRD)、傅里叶变换红外光谱(FT-IR)、Zeta电势分析等技术表明GO的交联和磷酸化成功。系统研究了溶液pH值、铀初始浓度、吸附时间和温度等因素的影响,得到了适宜吸附条件。吸附数据用Langmuir等温线模型拟合良好,最大吸附能力为495.05 mg/g。与准一级动力学模型相比,准二级动力学模型更好地拟合了吸附过程。

Abstract: The preparation of a novel phosphate-functionalized xanthan gum/graphene oxide (P-XG/GO) which is cross-linked with xanthan gum and functionalized with phosphoric acid was investigated for the selective adsorption of uranium from aqueous solutions in this study. The results from scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR) and Zeta potential analysis confirm that the cross-linking and phosphorylation modification are successful in our experiment. The effects of factors such as solution pH, initial concentration, adsorption time and temperature on the adsorption performance were studied and the most suitable adsorption conditions were obtained. The Langmuir isotherm model for adsorption data is well fitted, and the maximum adsorption capacity is 495.05 mg/g. Compared with the pseudo-first-order kinetic model, the pseudo-second-order kinetic model better fits the adsorption process.
