| Abstract: | Phenol and anisol fluorescence quenching in aqueous micellar solutions is investigated on addition of H 2 O 2. It is established that the efficiency of interaction of the phenol molecule in water with hydrogen peroxide is higher than of anisol. In the phenol-H 2 O 2 system, the buildup of phenol fluorescence occurs in the presence of an anionic-reagent detergent. A decrease in the efficiency of phenol fluorescence quenching by hydrogen peroxide in aqueous solutions in the presence of CTAB and triton X-100 micelles is observed. The micellar media increase the efficiency of interaction of anisol with a quencher in comparison with phenol. __________ Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 4, pp. 73–79, April, 2006. |
