TDA shows a significant fluorescence change upon the interaction of Hg2+ ion in DMF-water (v/v=1/1), while only minor changes in fluorescence intensity are observed with 18 other metal ions. Fluorescence enhancement by a factor of 15 is achieved upon selective interaction with Hg2+ ion. The Hg2+ ion detection process is found to be pH dependent; therefore, TDA could be feasible within a pH range of 4.0-7.0.en10.1111/cote.12122info:eu-repo/semantics/closedAccessArticle13113237Q3WOS:000348900400005Q2
