[Abstract]:The self-developed ultra-bright light-emitting diode excitation light source and fluorescence spectrum system were applied to the detection of fluorescent brighteners. The fluorescence brightener field rapid detection instrument was studied by using the front surface fluorescence technique. It has been applied to the quantitative determination of fluorescent brighteners in daily necessities. The content and migration of fluorescent brighteners in students' workbooks have been quantitatively analyzed by using self-assembled ultra-high light emitting diode excitation light source and fluorescence spectrum system. The rapid detection method of fluorescent brightening agent was established. The method of measuring the amount of fluorescent agent moving onto the finger was mainly determined. The self-assembled ultra-bright light emitting diode excitation light source-fluorescence spectrum system was used to simulate the actual usage of consumers. Measuring the fluorescence value of skin Care Mask before and after Pig skin coating to calculate the amount of fluorescent Agent migrating to the skin, this new detection device has the advantages of simple instrument, good stability and reproducibility, and no need to pretreat the sample. In situ rapid quantitative detection of the amount of fluorescent whitening agents migrated to the skin, In this paper, a method of detecting the amount of fluorescent brightener migration in accordance with the actual use of facial mask is established. Based on the study of the detection method of fluorescent brightener and its apparatus in student workbooks and skin care products, A qualitative and quantitative instrument for rapid detection of fluorescent brighteners was developed, and the performance of the instrument was tested. The accuracy, repeatability, linear range and stability of the instrument were measured. Detection time, contact current, protective grounding, The performance index of dielectric strength and appearance was tested. The standard and method of fast detection of fluorescent brightener in situ were studied and worked out. The qualitative analysis and quantitative determination of fluorescent brighteners in detergents were carried out. The method is simple and rapid. The content and mobility of fluorescent brightener in wet napkins and sanitary napkins were determined by using the self-developed fluorescence brightener rapid detector, and the pretreatment of the method was simple. In 10 min, rapid quantitative measurement of fluorescent brightening agent migration in wet napkins and rapid screening of fluorescent whitening agent migration in sanitary napkins were realized. The ultra-bright light emitting diode was used as the excitation light source system for fluorescent brightening agent detection. The excitation light source system is combined with the fluorescence spectrometer. The qualitative and quantitative determination of the content and migration of fluorescent brighteners in student workbooks and skin care products has been realized. This paper developed a fast detecting instrument for fluorescent brightener in situ. According to the need of engineering and commodity, the standard and method of fast detection instrument for fluorescent brightener were studied. The instrument has been applied to the qualitative and quantitative determination of fluorescent brighteners in detergents, wet napkins and sanitary napkins. At present, the instrument has been commercialized.
