| 英文摘要 | we report here a facile colorimetric sensor based on the n-acetyl-l-cysteine (nalc)-stabilized ag nanoparticles (nalc-ag nps) for detection of fe3+ ions in aqueous solution. the ag nps with an average diameter of 6.55 +/- 1.0 nm are successfully synthesized through a simple method using sodium borohydride as reducing agent and n-acetyl-l-cysteine as protecting ligand. the synthesized silver nanoparticles show a strong surface plasmon resonance (spr) around 400 nm and the spr intensity decreases with the increasing of fe3+ concentration in aqueous solution. based on the linear relationship between spr intensity and concentration of fe3+ ions, the as-synthesized water-soluble silver nanoparticles can be used for the sensitive and selective detection of fe3+ ions in water with a linear range from 80 nm to 80 mu m and a detection limit of 80 nm. on the basis of the experimental results, a new detection mechanism of oxidation-reduction reaction between ag nps and fe3+ ions is proposed, which is different from previously reported mechanisms. moreover, the nalc-ag nps could be applied to the detection of fe3+ ions in real environmental water samples.
