Gold nanoparticles (Au NPs) were synthesized by reducing HAuCl4 with sodium citrate. The sensitivity and selectivity of gold amalgam catalytic degradation of rhodamine B (RhB) system for mercury detection were investigated by fluorescence spectroscopy and ultraviolet-visible absorption spectroscopy. In the experiment, students' interest in scientific research and exploratory spirit will be stimulated, students' comprehensive experimental operation skills and subjective initiative will be improved, the understanding and application of nanoparticles preparation, characterization, catalytic reaction knowledge and metal ion analysis methods will be enhanced. Furthermore, the innovative thinking and scientific spirit of the students will be cultivated.

Key words: Au nanoparticles, Rhodamine B, Hg2+, Detection
