  ABSTRACT: Reduction of methylene blue (MB) occurred by photo irradiation at 280 - 370 nm wavelengths to a solution of MB in an ionic liquid, 1-butyl-3-methylimidazolium chloride (BMIMCl), which was confirmed by color change and UV-Vis measurement of the solution. Furthermore, the reduced MB was oxidized again by standing the solution under the conditions of light shielding at 50?C. The fluorescence spectra of the solution excited at 350 nm suggested that the photo-induced reduction probably took place via electron-transfer from BMIMCl to MB.
