摘要: Abstract Enhancement of peroxyoxalate chemiluminescence (PO-CL) intensity by a surfactant in the H2O2/bis(2,4,6-trichlorophenyl)oxalate (TCPO)/rhodamine B system was described. The effects 15 surfactants were evaluated comparing ratio relative CL (RCI) with to that blank each system. In preliminary study, H2O2/imidazole-HNO3 buffer/TCPO/rhodamine used study on PO-CL intensity. Fourteen reduced at 2% concentration, where their intensities ranged from 0.6 93.5%. Some these phenomena may be caused notable change pH occurred adding surfactant. Additionally, enhancement studied using (1) H2O2/TCPO/rhodamine and (2) buffer/TCPO/systems. 1, favorable (ranged 124 472%) observed 9 0.5% concentration. This result suggested several might play role as catalyst reaction. There no tendency enhance among types. 2, also 11 surfactants, which mainly fluorescent impurities used. Furthermore, detection detergent commercially available applied 1.
