摘要提案编号：9805118提案类型：研究者发起首席研究员：Lawrence Tavlarides隶属关系：锡拉丘兹大学：该资助是通过化学和运输系统部界面、运输和分离项目的分离和净化项目子项目授予的。首席研究员是雪城大学的Lawrence Tavlarides博士。该研究将导致一类有机陶瓷吸附剂选择性地提取特定的金属。这是一种通过结合两个完全不同领域的发展来开发选择性吸附剂的工程方法。有机螯合剂被无机单元功能化，使得它们可以参与溶胶-凝胶反应，从而并入多孔陶瓷结构中。这些材料被归类为III型聚合物。这些材料是新颖的，因为它们包含特定的化学功能，从而赋予有机陶瓷基体选择性。这项研究有可能对有关有毒和/或高价值金属的隔离和回收的技术产生重大影响。有毒金属的隔离在污染防治中具有极其重要的意义。从废催化剂中回收铂基金属对石油炼制和化工行业也具有重要意义。

AbstractProposal No: 9805118 Proposal Type: Investigator Initiated Principal Investigator: Lawrence Tavlarides Affiliation: Syracuse UniversityThis 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. Lawrence Tavlarides of Syracuse University. The research will lead to a class of organo-ceramic adsorbents to selectively extract specific metals. This is an engineering approach to the development of selective adsorbents by combining developments in two fairly disparate areas. Organic chelating agents are functionalized with an inorganic unit so that they can participate in sol gel reactions and thereby become incorporated into a porous ceramic structure. The materials are classified as type III polycerms. These materials are novel in that they incorporate specific chemical functionality and thus impart selectivity to the organo-ceramic matrix.The research has the potential to significantly impact technologies relating to the sequestration and recovery of toxic and/or high value metals. The sequestration of toxic metals is of extreme importance in pollution prevention and control. And the recovery of platinum based metals from spent catalysts is also very important to the petroleum refining and chemicals processing industries.
