▎ 摘　　要

Graphene oxide/gold nanoparticle (GO/GN) composites were prepared by citrate reduction that exhibited a strong resonance RS (RRS) peak at 370 nm. When KIO3 and H2O2 were added respectively, they reacted with KI to form I-3(-) ions that adsorbed on the GO/GN surfaces and the RRS intensity decreased due to the RRS energy of GO/NG being transferred to the receptor I-3(-) ions. So, a simple and sensitive GO/GN surface plasmon resonance (SPR) Rayleigh scattering (RS)-energy transfer (SPRRS-ET) analytical platform was fabricated and can be utilized to detect trace KIO3 and H2O2.
