GB/T 21883-2016 "Fluorescent Whitening Agents—Determination of Fluorescent Intensity" applies to the detection of fluorescent intensity for various fluorescent whitening agents, using a spectrophotometer (equipped with fluorescence accessories) for measurement. The sample is prepared into a standard concentration solution, and its fluorescent intensity is measured at specific excitation and emission wavelengths. The relative fluorescent intensity is calculated by comparing it with a standard sample. The standard specifies requirements for solution preparation, instrument calibration methods, and detection conditions to ensure the accuracy of fluorescent intensity determination.
