Abstract

Gold nanoparticles (Au NPs) were prepared by reducing HAuCl4 with sodium citrate. The sensitivity and selectivity of the gold amalgam catalytic degradation system for rhodamine B (RhB) in mercury detection were assessed using fluorescence and ultraviolet-visible absorption spectroscopy. This experiment aims to stimulate students' interest in scientific research and foster their exploratory spirit. It also enhances their comprehensive experimental skills and initiative, deepens their understanding and application of nanoparticle preparation, characterization, catalytic reactions, and metal ion analysis methods, and cultivates their innovative thinking and scientific mindset.
