| Abstract: | Ag nanoparticles(Ag NPs) were synthesized with the capping of citrate by chemical reduction.It was found that Ag NPs could enhance the chemiluminescence(CL) intensity of luminol and potassium ferricyanide system,moreover the CL intensity could be inhibited by resorcinol.Thus,a flow injection method was developed for the determination of trace resorcinol.The effect of luminol,potassium ferricyanide,sodium hydroxide and Ag NPs concentration on CL reaction was investigated,respectively.In the optimum condition... |
