Abstract

The invention discloses a mercury ion detection method which is characterized by comprising the following steps: (1) mixing a standard mercury ion solution and a gold nanocluster solution, and establishing a standard curve for detecting the fluorescence signal quenching of nanocluster and the mercury ion quantity; and (2) mixing a sample solution with the gold nanocluster solution, substituting the quenching intensity of the fluorescence signal of the nanocluster into the standard curve, thereby obtaining the content of the mercury ion in the sample. The method has the advantages that the sensitivity is high, the interference of other ions on detection of the mercury ion is slight, and selective detection of the mercury ion can be realized, so that the aim of rapidly detecting the mercury ion concentration is achieved. The method has wide application prospects in mercury ion detection.
