Abstract: 
The invention discloses a method for detecting potassium dichromate by a fluorescent carbon dot probe The method comprises the following steps: preparing the fluorescent carbon dot probe; preparing a mixed solution of the fluorescent carbon dot probe and a sample solution, and detecting the concentration of potassium dichromate in the mixed solution by a fluorescence quenching method The method has the beneficial effects that a fluorescent carbon dot is used as the probe, when the high sensitivity of potassium dichromate is detected by utilizing the characteristics that fluorescent lights of the fluorescent carbon dot are quenched via potassium dichromate, the detection limit of potassium dichromate can reach 25*10 mol/L, thus the detection process is easy and convenient to operate, high in sensitivity and excellent in selectivity, and the method can be used for detecting potassium dichromate in the mixed sample
