| dc.description.abstract | Sodium anthraquinone-2-sulphonate sensitizes the photoreduction of methylene violet in aqueous medium in the presence of hydrogen donors, isopropyl alcohol and benzhydrol, to give leuco methylene violet. Reduction takes place by reducing sodium anthraquinone-2-sulphonate produced through hydrogen abstraction by excited triplet state of sodium anthraquinone-2- sulphonate from the hydrogen donors. Effect of viscosity and role of electron transfer have been examined by adding ethylene glycol and triethylamine respectively. ϕLMV reaches a plateau at 4.0 and 1.7×10-2 mol dm-3 of IPA and BPH2 concentrations where ϕLMV = 1.7 and 1.0 respectively. Difference in maximum quantum yields in the case of IPA and BPH2 has been explained. ϕLMV is not afected by viscosity change. | en_US |
