| titleOfInvention | Method for rapidly detecting picric acid |
| abstract | The invention discloses a method for rapidly detecting picric acid. The method is based on a fluorescence quenching mechanism, namely, fluorescent substance molecules and extinguishing agent molecules act to generate a non-luminous substance, and specifically comprises the steps of dissolving a triphenylamine derivative in a solvent to form a solution, preparing the solution and picric acid solutions with different substance quantity concentrations in sequence to form mixed solutions with different proportions, detecting a fluorescence spectrum and an ultraviolet absorption spectrum of the mixed solution, and recording the change conditions of a fluorescence emission peak and an ultraviolet absorption peak in the mixed solutions with different proportions. The method has the characteristics of high sensitivity, large contrast, rapidness and the like when the picric acid is detected, and can realize the high-sensitivity detection of the picric acid in a water phase. The method is suitable for detecting the picric acid explosives in certain scenes in life. |
