Abstract

This communication reports the design and synthesis of a 4-(2-pyridylazo)-resorcinol (PAR)-functionalized polyacrylonitrile fiber that could not only remove heavy metal ions, especially mercury, but also can be applied for the simultaneous on-site naked-eye detection of these ions. The synthetic process of this colorimetric fiber was implemented under microwave irradiation, which enables greater efficiency and better performance. This rapid preparation method and dual-functional environmental material promise a new solution for the remediation of heavy metal pollution in water.
