AbstractProposal No: 9729849 Proposal Type: Investigator Initiated Principal Investigator: Anthony H. SkellandAffiliation: Georgia Institute of TechnologyThis grant is awarded through the Separations and Purification Program sub-element of the Interfacial, Transport and Separations Program of the Chemical and Transport Systems Division. The principal investigator is Dr. Anthony Skelland at the Georgia Institute of Technology. The research is directed towards the development of liquid membranes that exhibit a high level of stability without compromising permeability characteristics. The incorporation of polymeric additives to convert the membrane to non-Newtonian form is the central hypothesis of the research.Liquid membranes have a significant potential for continuous separations relating to the selective extraction of chemical species. Unfortunately, the system is flawed by problems associated with the stability of the membrane phase. The current research directly addresses the problem of stability with retention of transport rates. The project has relevance to the extraction of toxic contaminants in wastewater and to the selective extraction of compounds of interest to the fine chemicals and pharmaceutical industries.

摘要提案编号： 9729849 提案类型： 研究者发起的主要研究者： 安东尼·H SkellandAffiliation： 格鲁吉亚理工学院该补助金是通过化学和运输系统司的界面，运输和分离计划的分离和纯化计划子元素授予的。首席研究员是格鲁吉亚理工学院的安东尼·兰德博士。这项研究是针对发展的液体膜，表现出高水平的稳定性，而不损害渗透特性。加入聚合物添加剂将膜转化为非牛顿形式是该研究的中心假设。液膜在与选择性萃取化学物质相关的连续分离方面具有巨大潜力。不幸的是，该系统存在与膜相稳定性相关的问题。目前的研究直接解决的问题，保持运输率的稳定性。该项目涉及废水中有毒污染物的提取以及精细化学品和制药工业感兴趣的化合物的选择性提取。
