| Buffer Action of Reversed Micelles  | | | | Abstract
| The optical properties (absorption and fluorescence) of fluorescein sodium were investi-gated with changing the bulk pH value in aqueous, water-methanol mixed and dodecyl-ammonium propionate reversed micellar solutions. A strong buffer action was found in the reversed micellar solutions. The pKa values for the equilibrium between fluorescein mono-and di-anions in the ground and excited singlet states highly decreased in the reversed micellar solutions compared with those in non-micellar solutions. The micellar buffer action strongly affected the initial rate of the 1,3-diphenylisobenzofuran oxidation caused by the photosensitization of fluorescein. The buffer action was closely related to the solubilized water content. | | | |
