  • MERCURY SENSOR AND METHODS OF USE
    Publication number: 20160097754
    Abstract: The invention relates to non-fluorescent or low-fluorescent compounds for contact with mercury ions to produce fluorescent compounds as a detector for mercury. The fluorescence produced by the contact of the non-fluorescent or low-fluorescent compounds with mercury ions has an intensity greater than the intensity produced by the contact of the non-fluorescent or low-fluorescent compounds with other metals. The fluorescent compounds may be used as sensors/detectors for mercury ions in various samples. Methods for detecting and calculating the concentration of mercury ions in samples are also disclosed.
