It is of great significance to separate and recovery trace metallic ions from the natural environment, which is very important in the development of modern industry, environmental treatment, utilization of the resources, water and soil renovation and human health. Based on the molecular recognition principle, we will firstly focus on the discovery of novel highly selective or specific binding receptors for the metallic ions. Then, highly selective capture agents for metallic ions with dual separation and detection properties will be designed and synthesized, and the related issues of product engineering will be intensively investigated. Finally, novel principle, novel methodology and novel technology will be developed to separate and recovery trace metallic ions from complex solutions, especially toxic heavy metallic ions, noble metallic ions and energy-related metallic ions. (1) Using molecular modelling technology and fluorescent sensing technology, highly selective organic receptors for metallic ions will be designed, synthesized and evaluated. (2) With the combination of supporting matrix and the as-synthesized receptors with fluorophores, novel capture agents for metallic ions, with dual detection and separation properties, will be developed, and the relationship between strctures and activities will also be evaluated. (3) Based on different systems and metallic ions, studies on the regenerative property and stability of the capture agents will be conducted. The accomplishment of this project will develop various excellent capture agents for metallic ions, which have detection and separation dual properties, and will contribute to the development of Chemical Product Engineering discipline.
