In this paper, a method based on the fluorescing characteristics of chlorophyll a in water to determine the chlorophyll a content in water is developed. The pulsed high-brightness lightemitting diode is used as the light source, and the emitted light is irradiated to the measured by a 470 nm filter. In the water body, the chlorophyll a in the water body is excited, and emits fluorescence longer than the wavelength of the excitation light. The fluorescence intensity and the concentration of chlorophyll have a linear relationship within a certain range, and the emitted fluorescence is received by the photo cell and generates an electric signal according to the electric signal. Strength and weakness to calculate the change of chlorophyll a content in the measured water. The method has the characteristics of reagent-free, movable and real-time detection, and is very suitable for safety early warning monitoring and emergency monitoring of large-area long-distance water source water quality in China.
