Abstract: This paper detected and analyzed nine kinds of fluorescent brighteners in textiles and toilet paper. Through ultrasonic extraction of textiles or toilet paper with 30% Nmine N-dimethylformamide aqueous solution as the solvent, the sample solution was analyzed by high performance liquid chromatography-diode array-fluorescence (HPLC-DAD-FLD). The qualitative analysis was carried out by comparing the retention time and spectral characteristics between the samples and the reference materials. And the peak area of fluorescent brightener components in compared samples and standard materials was quantified by external standard method. Based on the optimization of extraction solvent, extraction temperature, extraction time, and chromatographic conditions, a detection method of nine fluorescent brighteners in textiles and toilet paper by HPLC-DAD-FLD was established. The method is simple, sensitive, accurate, and suitable for the rapid selection and detection of fluorescent bleaching agents in textiles and toilet paper.
