Abstract

A rhodamine-based fluorescent and colorimetric chemodosimeter for the rapid detection of Hg²⁺ ions in aqueous media was developed. The system, which utilizes an irreversible Hg²⁺-promoted oxadiazole forming reaction, responds instantaneously at room temperature in a 1:1 stoichiometric manner to the amount of Hg²⁺. The selectivity of this system for Hg²⁺ over other metal ions is remarkably high, and its sensitivity is below 2 ppb in aqueous solutions.
