description	The invention discloses a mercury ion optical fiber detector based on the fluorescence quenching of cyclometalated iridium fluorescent complex, which relates to the field of detecting mercury ion concentration in a liquid environment and is characterized in that the mercury ion optical fiber detector comprises a highly integrated, orderly and serially connected power supply, an excitation light source, a light filtering device, optical fiber, a mercury ion detecting probe, a light signal detector, a signal processing system and a digital display unit; the surface of the mercury ion detecting probe is fixed with solid cyclometalated iridium fluorescent complex containing heterocyclic sulfur ligand through chemical bonds. The complex generates fluorescence under the irradiation of excitation light, and the fluorescence complexes with the mercury ion in the water, and then a fluorescence quenching effect is generated. After being applied and implemented, the optical fiber detector of the invention has beneficial
