NOVELTY - The utility model claims a measuring device of oxidation graphene concentration, belonging to the technical field of new material detection. The measuring device comprises: a light source, a cuvette and a light absorbing device, the light source, the cuvette, the light absorbing device are arranged on the same horizontal line sequentially the light source, cuvette and light absorbing device are placed in the light shielding cover. The utility model is based on the principle of Langberbier law, can deduce the relationship of the intensity of the light after passing through the sample, by detecting the intensity of the light of the sample to calculate the concentration of the sample. The utility model compared with the traditional detecting device, the operation is more convenient, the step is less, the measuring device of the utility model detects the concentration of the graphene, only needs to measure the fixed wavelength of the absorption light intensity, does not need to run a certain wavelength range, saves time, high detection efficiency.
