水体中汞离子在含氮杂环功能有机吸附剂的强化富集去除研究

Mercury ion is considered as one of the most toxic cation which puts human health and the environment at risks. Due to their durability, easy transference and high biological accumulation, exposure to mercury and its compounds can cause a series of serious health problems, Therefore, the development of new materials for high-efficiency removal of mercury ion is of great importance and highly desirable.. The purpose of this project is to synthesis of nitrogen-containing heterocyclic functional organic adsorbents and the recognition and removal of mercury ions. The main contents including: 1) the synthesis of different nitrogen-containing heterocyclic molecular monomers and to Screen of optimal mercury ion recognition compounds. 2) To prepare nitrogen-containing heterocyclic functional organic materials with different configurations, and the adsorption capacity of mercury ions will also investigate; 3) The mechanism of coordination of nitrogen-containing heterocyclic functional organic materials with mercury ions will discuss, and also provides methods for targeting adsorption and recovery of other heavy metal ions. We will explore the new phenomena and rules in the process of coordination of nitrogen-containing heterocyclic functional organic materials with mercury ions after comparing and analyzing of the experimental results, and to develop methods and techniques for the removal and recovery of mercury ions with high efficiency and selectivity.. In a word, we will find the law and phenomenon in the adsorption process and the relationship between the structure properties and adsorption properties of nitrogen-containing heterocyclic functional organic materials. We also discuss the removal mechanism of mercury ions.

汞离子被认为是危害人类健康和环境的最有毒阳离子之一。汞及其化合物具有持久性强、易迁移、生物累积量高等特点。因此，开发高效去除汞新材料具有重要的现实意义和广泛的应用前景。本项目拟开展含氮杂环功能有机吸附剂的合成及对水体中的汞离子识别及去除的研究，主要包括三个方面：1）合成不同的含氮杂环分子单体，筛选出最优的汞离子识别化合物；2）制备出不同构型的含氮杂环功能有机材料，并考察其对汞离子的吸附能力；3）含氮杂环功能有机材料与汞离子的配位机理研究并指导其它重金属离子的靶向吸附和回收。通过对实验结果的比较和分析，探索含氮杂环功能有机材料与汞离子配位过程中所表现出来的新现象和规律，发展出具有高效、高选择性汞离子去除和回收方法和技术。. 总之，通过此项研究，将发现吸附过程中表现出来的规律和现象，并辅以现代仪器测试手段，研究含氮杂环功能有机材料的结构性质与吸附性能的关系，并探明汞离子去除机理。
