Naked-eye and Selective Detection of Mercury (II) Ions in Mixed Aqueous Media Using a Cellulose-based Support

A test paper for high-selectivity detecting Hg(2+) ions in mixed acetonitrile-water solutions has been achieved using a bis(ferrocenyl) azine, as chromogenic chemosensor molecule, and a solid cellulose fibre, as a substrate. Depending on the amount of mercury ions in contact with the detecting molec...

Descripción
Sumario:A test paper for high-selectivity detecting Hg(2+) ions in mixed acetonitrile-water solutions has been achieved using a bis(ferrocenyl) azine, as chromogenic chemosensor molecule, and a solid cellulose fibre, as a substrate. Depending on the amount of mercury ions in contact with the detecting molecule a spectacular color change in the cellulose indicator is produced, being possible to determine the concentration of Hg(2+) ions either by naked eye or spectroscopically.
