Abstract

A method for detecting mercury (Hg2+) ions in an aqueous solution is described. The method includes contacting the aqueous solution with a chemosensor to form a mixture; and monitoring a change in a fluorescence emission profile of the chemosensor in the mixture to determine the presence or absence of Hg2+ ions in the aqueous solution. The chemosensor includes pyrene silica nanoparticles where at least one pyrene is bonded to a surface of a silica nanoparticle through an amide bond with a formula of, pyrene-C(═O)NHR-silica nanoparticle, and where R is an alkyl chain.
