| Abstract: | Based on a great fluorescence Stokes shift of sulfosalicylic acid, which has been observed in the experiment, a mechanism of intramolecular proton transfer of sulfosalicylic acid has been described. A rapid fluorimetry for the determination of sulfosalicylic acid in acidic tin electrolating solution has been established. With this method, only 5 to 10 minutes were needed for one time of determination, and the determination was not interfered by the coexisting components in the electroplating solution. The relative standard deviation was less than 3%. |
