Detection of Hg2+ ions in aqueous medium using an indole-based fluorescent probe: Experimental and theoretical investigations

Popis výsledku v původním jazyce

Mercury pollution is a widespread danger to human health and environment. Due to limitations associated with the existing Hg2+ chemosensors, development of new, efficient and selective chemosensors capable of sensing mercury ions in aqueous medium remains a demanding area of research. In this regard, an indole-based fluorescent probe has been synthesized and characterized by detailed spectroscopic analysis. The probe showed a high selectivity and sensitivity towards Het by giving significant fluorescence quenching over other tested cations in H2O/DMF (7:3, v/v) medium. The association constant (K-a) was 6.4 x 10(3) M-1 between sensor and Hg2+. The detection limit of sensor to Hg2+ was found to be 0.143 mu M (143 nM). The experimental results have been verified with Density Functional Theory.
