A Phenazine Hydrochloride for the Selective Detection and Removal of Mercury(ІІ) Ions in Water

Abstract

A material that can simultaneously detect and remove toxic heavy metal Hg 2 + ions are still needed in urgent. Herein, we report that an efficient, simple and water-soluble phenazine hydrochloride (DAPH) chemosensor for colorimetric and fluorogenic detection of Hg 2 + in pure water. The fluorescent and UVvis detection limits for Hg 2 + are low. Meanwhile, the chemosensor is able to effectively remove Hg 2 + in pure water through inductively coupled plasma (ICP) analysis. A series of experimental results showed that the chemosensor successfully used to real-time detect and remove toxic heavy metal Hg 2 + ions from water via a simple deprotonation and destroyed phenazine-based hydrochloride π À π stacking interactions. In addition, the fabricated silica gel plates are also demonstrated excellent selectivity towards Hg 2 + ion without interfering.
