摘要：

We have developed a simple, sensitive and selective colorimetric method for the detection of cadmium(II) (Cd2+) using gold nanoparticles modified with 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole. Organic solvents or additives are not required. It is found that Cd2+ induces the aggregation of the modified Au-NPs via chelation, leading to a color change from red to blue. This change can be seen with bare eyes, and monitored by UV-vis spectroscopy, transmission electron microscopy and dynamic light scattering. The detection limit is 30 nM (at a signal-to-noise ratio of 3). The new approach was successfully applied to the detection of Cd2+ in spiked samples of tap water and lake water, and the results agree well with those obtained by flame atomic absorption spectroscopy.
