摘　　要：铀是重要的核燃料,也是发展核电的前提条件之一,而它具有重金属毒性和放射性,可对人类的生存和发展构成潜在的威胁.铀的检测对资源开发、健康维护和环境保护都非常重要.要高效地获得铀资源并防止铀污染,就必须开发高效无毒的铀配位剂.本文利用间苯二甲醛与吡咯发生的反应制备了一种新型的双极双齿配体isophthalaldehyde-tetrapyr-role(IPTP),并研究了其与铀酰离子进行配位作用的共振光散射光谱及机理,初步探讨了其用作铀配位剂开发分离分析新方法的可能性.Uranium is one of the most important nuclear fuels and one of the prerequisites for the development of nuclear power.But it has heavy metal toxicity and radioactivity,which can pose a potential threat to human survival and development.Uranium detection is very important for resource development,health maintenance and environmental protection.In order to obtain uranium resources efficiently and prevent the pollution of uranium,it is necessary to develop highly efficient and nontoxic uranium coordination agents.This study synthesized a dipolar bidentate ligand,isophthalaldehyde-tetrapyrrole （IPTP）,by the condensation reaction of an isophthalaldehyde molecule with four pyrrole molecules.The resonance light scattering spectra and the mechanism of its coordination with uranyl ion were studied,and the possibility of using it to develop a new method for the separation and analysis of uranium coordination agents was discussed.
