摘要：
The chemiluminescence (CL) of luminol–H2O2 system is strongly enhanced on addition of nanoparticles composed of a gold/silver alloy (ratio 5:4). The effect is attributed to a catalytically enhanced decomposition of H2O2 to produce reactive oxygen species. A reaction mechanism is proposed. Organic compounds containing hydroxy, amino, or thiol groups (such as amino acids, dopamine, pyrocatechol) can inhibit the CL signal of the system. It is concluded that the system has a large potential in terms of the determination of such compounds.
