Abstract

See full text

A method of detecting Hg2+ ions in an aqueous solution is described. The method includes contacting the aqueous solution with a metal-organic framework (MOF) chemosensor composite to form a mixture and monitoring a change in an absorption and/or a fluorescence profile of the MOF chemosensor composite in the mixture to determine a presence or absence of Hg2+ ions in the aqueous solution. The MOF chemosensor composite includes fluorescein hydrazide (FH); and a MOF, including nickel as a metal ion and at least one trimesic acid (BTC) ligand. A hydrazide group on the fluorescein hydrazide coordinates to the metal ion of the MOF.
