| description | The invention belongs to the technical field of nano material preparation, and particularly relates to a preparation method of nitrogen-doped fluorescent carbon quantum dots and application of the nitrogen-doped fluorescent carbon quantum dots to detection of mercury ions. The preparation method comprises the following steps: mixing and grinding a carbon source and a functional monomer, and then carrying out a reaction through a hydrothermal synthesis method to prepare the nitrogen-doped fluorescent carbon quantum dots, the carbon source is alginate; the functional monomer is histidine; the mass ratio of the carbon source to the functional monomer is 2: (0.8-1.5). The yield of the nitrogen-doped fluorescent carbon quantum dots prepared by the preparation method is not lower than 60%, and the nitrogen-doped fluorescent carbon quantum dots are very suitable for industrial production and application. The nitrogen-doped fluorescent carbon quantum dots prepared by the preparation method are used for detecting merc |
