Abstract
Gold colloids with nanoparticles of different sizes were found to enhance the chemiluminescence (CL) of the luminol−H2O2 system, and the most intensive CL signals were obtained with 38-nm-diameter gold nanoparticles. UV−visible spectra, X-ray photoelectron spectra, and transmission electron microscopy studies were carried out before and after the CL reaction to investigate the CL enhancement mechanism. The CL enhancement by gold nanoparticles of the luminol−H2O2 system was supposed to originate from the catalysis of gold nanoparticles, which facilitated the radical generation and electron-transfer processes taking place on the surface of the gold nanoparticles. The effects of the reactant concentrations, the size of the gold nanoparticles. and some organic compounds were also investigated. Organic compounds containing OH, NH2, and SH groups were observed to inhibit the CL signal of the luminol−H2O2−gold colloids system, which made it applicable for the determination of such compounds.Keywords
