主 题:chemiluminescence potassium permanganate emitting species energy transfer
摘 要:Chemiluminescence (CL) phenomenon of hydrogen peroxide with potassium permanganate in the presence of sodium hydrogen carbonate was *** of the surfactant on the CL system were *** surfactants could effectively increase the CL *** scavengers and organic reagents such as nitro blue tetrazolium chloride (NBT),cytochrome c,sodium azide,ascorbic acid,thiourea,tert-butanol and dimethyl sulphoxide were used to study the emitting *** emission spectrum was recorded and the results showed that the maximal emission wavelengths of NaHCO3-H2O2-KMnO4 system were 440 and 634 *** mechanism was discussed based on electron spin resonance (ESR) spectra,fluorescence spectra and UV-vis absorption *** addition of rhodamine B or uranine into this CL system enhanced the CL *** was due to part of the energy transfer from singlet oxygen and excited triplet dimers of two CO2 molecules to rhodamine B or *** CL could be induced by excited rhodamine B or uranine.
