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 UV‐vis 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−π stacking interactions. In addition, the fabricated silica gel plates are also demonstrated excellent selectivity towards Hg 2+ ion without interfering.
