摘要: 发酵生物甲烷的菌群可以吸附Pb2+等重金属而在沼液和沼渣中富集;因此,在生物甲烷系统研究过程中,Pb2+等重金属离子的检测和处理是沼液和沼渣处理的关键问题之一。18-冠-6具有选择性络合Pb2+的能力,研究者们将18-冠-6的Pb2+识别特性与聚N-异丙基丙烯酰胺的相变行为特性相结合制备了一系列Pb2+识别响应型智能高分子功能材料。本文综述了基于18-冠-6和聚N-异丙基丙烯酰胺的离子识别响应型智能高分子材料在检测和去除Pb2+等方面的研究进展。

Abstract: Some of the anaerobic bacterium fermented bio-methane can adsorb heavy metals, such as Pb2+, which are enriched in biogas slurry and residue. For this reason, the detection and removal of heavy metal ions, such as Pb2+ ion in biogas slurry and residue is one of the key problems in the study of bio-methane systems. 18-crown-6 has remarkable recognition ability towards Pb2+ ion. The Pb2+ ion-recognition-responsive smart materials composed of 18-crown-6 and poly(N-isopropylacrylamide) (PNIPAM) have been developed. In this paper, the progress of investigation on Pb2+ ion-recognition-responsive smart polymeric materials based on 18-crown-6 and poly(N-isopropylacrylamide) for detection and removal of Pb2+ is reviewed.
