Novel Silica-Based Hybrid Adsorbents: Copper(II) Adsorption Isotherms and Thermodynamics 作者:Hu, KY (Hu, Keyan)[ 1 ] ; Liu, JS (Liu, Junsheng)[ 1 ] ; Chen, XH (Chen, Xinghua)[ 1 ] ; Xu, M (Xu, Min)[ 1 ] ; Wang, KC (Wang, Kechun)[ 1 ] ASIAN JOURNAL OF CHEMISTRY 卷: 26 期: 13 页: 3845-3848 子辑: A 出版年: JUL 2014 查看期刊信息 摘要 In this study, copper(II) adsorption isotherms and thermodynamic data have been investigated using a hybrid membrane as an adsorbent. It is found that copper(II) adsorption on sample D followed the Freundlich isotherm model. Moreover, it is found that the adsorption capacity of copper(II) on sample D increases with an increase in solution temperature and the Delta G values are changed from positive to negative as the temperature increased, suggesting that copper(II) adsorption is an endothermic and spontaneous in nature as the solution temperature was elevated to higher level. In addition, based on intraparticle diffusion, it is confirmed that copper(II) adsorption is not governed by intraparticle diffusion and diffusion-controlled adsorption mechanism might be the major control process. This finding is meaningful in the removal of copper(II) from aqueous solution using hybrid membrane as an adsorbent. 关键词 作者关键词:Hybrid membrane; Adsorption; Isotherms; Thermodynamics; Copper(II) removal KeyWords Plus:AQUEOUS-SOLUTION; REMOVAL; EQUILIBRIUM; KINETICS; METALS; ACID 作者信息 通讯作者地址: Liu, JS (通讯作者) Hefei Univ, Dept Chem & Mat Engn, Key Lab Membrane Mat & Proc, 99 Jinxiu Rd, Hefei 230601, Peoples R China. 地址: [ 1 ] Hefei Univ, Dept Chem & Mat Engn, Key Lab Membrane Mat & Proc, Hefei 230601, Peoples R China 电子邮件地址:jsliu@hfuu.edu.cn 基金资助致谢 基金资助机构 授权号 National Natural Science Foundation of China 21076055 Significant Foundation of Educational Committee of Anhui Province ZD2008002-1 2th National-level College Students' Innovative Entrepreneurial Training Plan Program 201211059010 查看基金资助信息 出版商 ASIAN JOURNAL OF CHEMISTRY, 11/100 RAJENDRA NAGAR, SECTOR 3,, SAHIBABAD 201 005, GHAZIABAD, INDIA 类别 / 分类 研究方向:Chemistry Web of Science 类别:Chemistry, Multidisciplinary 文献信息 文献类型:Article 语种:English 入藏号: WOS:000343763700019 ISSN: 0970-7077 电子 ISSN: 0975-427X 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: AR7ML Web of Science 核心合集中的 "引用的参考文献": 13 Web of Science 核心合集中的 "被引频次": 0 |
