摘要

Gold nanoparticles (AuNPs) modified by 8-hydroxy-quinoline (8-HQ) and stabilized by polyvinylpyrrolidone (PVP) were used for highly selective and sensitive colorimetric detection of Hg~(2+) based on the quick aggregation of AuNPs leading to a color change from wine red to gray. The limit of Hg~(2+) detection in real environmental water samples is 4.0 × 10~(-7) M by the naked eyes and 1.0 × 10~(-8) M by UV-vis spectroscopy.
