摘要：

Mercuric ions, Hg[II], can be detected and quantitated by measuring the surface plasmon resonance (SPR) signal when a gold film treated with 1,6-hexanedithiol (HDT), which produced a self-assembled monolayer, is exposed to mercury ions in aqueous solution. Changes in the SPR signal allowed not only quantification of the concentration of Hg[II] in solution from 1.0 nM to 1.0 mM but also selective detection of Hg[II] ions when present in mixtures containing Pb[II], Ni[II], Zn[II], and Cu[II] ions.
