Abstract

A new, simple, sensitive and selective spectrofluorimetric method for the determination of trace amounts of Hg2+ in hazardous wastes of fluorescent lamps using chemosensor neutral red dye is developed in acetonitrile at pH 6.6. The Hg2+ can remarkably quench the fluorescence intensity of neutral red dye in acetonitrile at λex = 380 nm. The lowering of fluorescence intensity of neutral red dye is proportional to the concentration of Hg2+ and it is used as optical sensor for its assessment. The dynamic range found for the determination of Hg2+  concentration is 2.3 × 10-9 – 8.0 ×10-6 mol l−1 with a detection limit of 1.0 ×10−11 mol l−1.
