Highly efficient removal and degradation of toxic compounds with novel host molecule-metal ion complexes having enzyme-like activities

本研究的目的是开发高效的环境净化系统，利用具有类似酶活性的新型主体分子-金属离子络合物来实现危险化学品的去除和随后的解毒。以有机磷(如敌百威、敌敌畏和对氧磷)和氨基甲酸酯(如西维因和残杀威)农药为例，研究了它们从水中的去除以及随后的水解降解以降低其神经毒性。研究结果为实际使用的环境净化材料和系统的进一步设计和开发提供了指导。

The present study was conducted with a view to developing highly efficient environmental purification systems by which the removal and subsequent detoxification of hazardous chemicals can be achieved with novel host molecule-metal ion complexes having enzyme-like activities. Taking organophosphate (e.g., fenitrothion, dichlorvos, and paraoxon) and carbamate (e.g., carbaryl and propoxur) pesticides as examples, their removal from water, followed by the hydrolytic degradation to reduce their neurotoxicity, was examined. The obtained results provide guidelines for the further design and development of environmental purification materials and systems for practical use.
