Application of extraction and adsorption to the alkylpyrazine removal from wastewater 作者:Wang, WQ (Wang, Weiqiang)[ 1 ] ; Lv, J (Lv, Jian)[ 1 ] ; Yang, JM (Yang, Jianming)[ 1 ] ; Mei, SN (Mei, Suning)[ 1 ] ; Li, YN (Li, Yani)[ 1 ] ; Wan, H (Wan, Hong)[ 1 ] ; Yu, QW (Yu, Qinwei)[ 1 ] DESALINATION AND WATER TREATMENT 卷: 54 期: 1 页: 147-155 DOI: 10.1080/19443994.2013.879839 出版年: APR 3 2015 查看期刊信息 摘要 Application of extraction and adsorption process to the alkylpyrazine removal from wastewater was investigated. The detailed extraction process was studied. It was found that the alkylpyrazine content in the water phase after extraction was decreased to 0.3% or less from about 3.0% (wt.). Extractant was recovered by concentrating the water phase and then the wastewater generated from concentration process was disposed by adsorption treatment in order to further lower the level of alkylpyrazine in wastewater. Adsorption of simulated wastewater containing 2,3-dimethylpyrazine on the different resins was also investigated. Among the resins of various grades used, the XDA-200 had the best properties in decontamination of aqueous 2,3-dimethylpyrazine solutions. The chemical oxygen demand (COD) of authentic wastewater generated from extraction process after adsorption treatment with XDA-200 was less than 1,000 mg/L and its removal percentage was above 90%. It was shown that regeneration of the adsorbent bed could be effectively performed with ethanol. Based on the extraction and adsorption experimental results, more than 98% of COD in the wastewater was removed. 关键词 作者关键词:Extraction; Adsorption; Wastewater treatment; Alkylpyrazine KeyWords Plus:ORGANIC POLLUTANTS; AQUEOUS-SOLUTION; ETHANOLAMINE; DERIVATIVES; OXIDATION; PYRAZINE; ETHYLENEDIAMINE; TECHNOLOGIES; MORDENITE; AMINATION 作者信息 通讯作者地址: Wang, WQ (通讯作者) 显示增强组织信息的名称 Xian Modern Chem Res Inst, 168 Zhangba Rd East, Xian 710065, Peoples R China. 地址: 显示增强组织信息的名称 [ 1 ] Xian Modern Chem Res Inst, Xian 710065, Peoples R China 电子邮件地址:wqwang204@gmail.com 基金资助致谢 基金资助机构 授权号 National Ministry of Science and Technology 查看基金资助信息 出版商 TAYLOR & FRANCIS INC, 530 WALNUT STREET, STE 850, PHILADELPHIA, PA 19106 USA 类别 / 分类 研究方向:Engineering; Water Resources Web of Science 类别:Engineering, Chemical; Water Resources 文献信息 文献类型:Article 语种:English 入藏号: WOS:000350678100001 ISSN: 1944-3994 eISSN: 1944-3986 期刊信息 Impact Factor (影响因子): Journal Citation Reports® 其他信息 IDS 号: CC9HC Web of Science 核心合集中的 "引用的参考文献": 26 Web of Science 核心合集中的 "被引频次": 0 |
