0604368TarabaraThe objective of this research is to develop a new method of aqueous mercury removal based on polymer-supported molecular traps with a cage structure that are highly selective for mercury and also easily regenerable. The proposed method is expected to be cost-effective because of these two characteristics. Existing methods of mercury binding by complexing agents are based on soft ligands that typically include nitrogen atoms in their structures. However, copper forms much more stable complexes with amines than mercury, and this results in poor efficiency of mercury removal by such complexing agents. In the proposed research, an interdisciplinary team of chemists and environmental engineers will synthesize polymer-supported molecular traps. They also will test the hypothesis that polymeric materials based on cage-based precursors can be developed for aqueous mercury removal. This proposal fits the criteria for the SGER program in that it the idea is novel and innovative and the project satisfies the high risk-high reward criterion.

0604368 Tarabara本研究的目的是开发一种基于聚合物负载的具有笼状结构的分子捕集器的水溶液汞去除新方法，该分子捕集器对汞具有高度选择性并且易于再生。由于这两个特点，预计所提出的方法是具有成本效益的。现有的通过络合剂结合汞的方法基于通常在其结构中包括氮原子的软配体。然而，铜与胺形成比汞更稳定的络合物，这导致通过这种络合剂除去汞的效率差。在拟议的研究中，一个由化学家和环境工程师组成的跨学科团队将合成聚合物支持的分子陷阱。他们还将测试基于笼基前体的聚合物材料可用于水溶液汞去除的假设。该方案符合SGER计划的标准，因为它的想法是新颖的和创新的，该项目满足高风险高回报的标准。
