▎ 摘　　要

NOVELTY - Fluorescent sensing array detection platform for various plasticizers comprises N,N-dimethylformamide as boron-doped graphene quantum dots (B-GQDs) solution of the solvent and the boron-doped graphene quantum dot (B-GQDs) solution using cyclohexane (CH) as the solvent. The B-GQDs solution whose solvent is dimethylformamide obtains the fluorescence intensity of the fluorescence characteristic peak under the excitation of ultraviolet light with a wavelength of 350 nm, and the fluorescence data at 391 nm, 413 nm and 434 nm as array points 1, 2 and 3. The B-GQDs solution whose solvent is CH is excited by ultraviolet light with a wavelength of 350 nm to obtain the fluorescence intensity of the fluorescence characteristic peak, the fluorescence data at 386 nm, 408 nm and 430 nm are used as array points 4, 5 and 6, and constructs a 3×2 fluorescent sensor array. USE - Used as fluorescent sensing array detection platform for various plasticizers. ADVANTAGE - The method has simple steps, satisfactory specificity, reproducibility, stability and practicability, and application potential. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for fluorescent sensing array detection method for multiple plasticizers, comprising diluting 5 μl B-GQDs solution to 10 ml with dimethylformamide and CH of solvents respectively, preparing B-GQDs stock solution that the solvent is dimethylformamide and the B-GQDs stock solution that the solvent is CH, preparing the plasticizer sample to be tested into a sample solution with dimethylformamide and CH two solvents respectively, mixing 20 μL B-GQDs stock solution with dimethylformamide as the solvent and 400 μL of the sample solution with dimethylformamide as the solvent under excitation by ultraviolet light with a wavelength of 350 nm, obtaining the fluorescence intensity of the fluorescence characteristic peak, and taking the fluorescence data at array points 1, 2 and 3, namely 391 nm, 413 nm and 434 nm, mixing 20 μL of the B-GQDs stock solution whose solvent is CH with 400 μL of the sample solution whose solvent is CH by excitation with a wavelength of 350 nm ultraviolet light, obtaining the fluorescence intensity of the fluorescence characteristic peak, obtaining the fluorescence data at array points 4, 5 and 6, i.e. 386 nm, 408 nm and 430 nm, after obtaining the data of the six array points, performing linear fitting on the data of each array point, and selecting the array point with the strongest correlation of the fitting result as the advantage point for the quantitative detection of the plasticizer.
