中文摘要： 新型溴代阻燃剂(Bromide Flame Retardants, BFRs)是样品中神经毒性风险的主要来源，目前尚无有效手段对环境中神经毒性效应化合物进行有效识别。本项目在我们前期从事分子印迹技术工作的基础上，拟运用理论化学计算方法，筛选分子印迹体系以及预测印迹聚合物的性能，为印迹聚合物的制备和应用提供理论指导；结合印迹技术与电纺丝方法，重点研究制备新型BFRs分子印迹纳米纤维膜，摸索其制备的关键技术，实现高效分离此类物质；将功能化的纳米纤维固定于电化学传感界面上，偶联电化学测试手段，以期建立起对新型BFRs分子的快速、高灵敏和高稳定检测方法。项目研究对新型BFRs污染物的应急监测和简易监测具有实际意义。

英文摘要： Neurotoxicity induced by environmental pollutants has been of major public and scientific concern due to the serious health threats to humans, especially infants and children. Brominated flame retardants (BFRs) have been beneficially used in many consumer products such as polymers, furniture, computers, and television sets. However, large production volumes, modes of application, and intrinsic chemical-physical properties of some BFRs have also rendered these to be found at increasing levels in the environment, wildlife, and humans. Some of the BFRs have recently attracted much attention due to their persistence in the environment and widespread global distribution. BFRs have also been studied in regard to their potential as developmental neurotoxicants. However, there is no effective means to identify the compounds in the environment. On the basis of our previous work in molecular imprinting technique, we want to screen molecularly imprinted systems and forecast performance of imprinted polymers by Theoretical and Computational Chemistry, it is to provide theoretical guidance for the preparation and application of imprinted polymers; then, in order to achieve efficient separation of these substances, this project will focus on the preparation of the novel BFRs molecular imprinted nanofibers by combinating the i
