Colorimetric Detection of Hg(II) Ion Using Silver Nanoparticles Capped with 3-Hydroxybenzoic Acid
In this paper, we report for the first time thesimple method for detection of Hg(II) ion in anaqueousmedium using silver nanoparticles capped with 3-hydroxybenzoic acid. Silver nanoparticles capped with 3-hydroxybenzoic acid were preparedby reduction of the silver ion with 3-hydroxybenzoic acid and...
