Abstract
A film for detecting fluoride concentrations is disclosed. The film includes an organic matrix having a lipophilic aluminum compound incorporated therein. The lipophilic aluminum compound is adapted to selectively bind with fluoride ions via a binding interaction. The fluoride is detectable through optical or electrochemical detection of the binding interaction.
Claims31
A film for detecting fluoride, the film comprising:
- an organic matrix;
- and
- a lipophilic aluminum compound incorporated within the organic matrix, the lipophilic aluminum compound adapted to selectively bind with fluoride ions via a binding interaction, the fluoride being detectable through optical or electrochemical detection of the binding interaction.
A film for optically detecting fluoride, the film comprising:
- an organic matrix;
- a lipophilic aluminum compound incorporated within the organic matrix, the lipophilic aluminum compound adapted to selectively bind with fluoride ions;
- and
- a lipophilic pH chromoionophore incorporated within the organic matrix, the chromoionophore adapted to transduce to an optical signal the binding interaction.
A method of making a sensor for optically detecting fluoride, the method comprising:
- incorporating a lipophilic aluminum compound into an organic matrix, the lipophilic aluminum compound adapted to selectively bind with fluoride ions, and the fluoride being detectable through optical or electrochemical detection of the binding interaction;
- and
- dissolving the organic matrix having the aluminum compound therein in a solvent.
A sensor for detecting fluoride, the sensor comprising:
- an organic matrix;
- and
- a lipophilic aluminum compound incorporated within the organic matrix, thereby forming a film, the lipophilic aluminum compound adapted to selectively bind with fluoride ions via a binding interaction, the fluoride being detectable through optical or electrochemical detection of the binding interaction;
- wherein the film is adapted to be established on a substrate or between two aqueous phases.
A method for electrochemically detecting fluoride, the method comprising:
- binding fluoride ions to a lipophilic aluminum compound incorporated in an organic matrix;
- and
- detecting, through an electrochemically detectable signal, the binding of the fluoride ions to the lipophilic aluminum compound.
A method for optically detecting fluoride, the method comprising:
- binding fluoride ions to a lipophilic aluminum compound incorporated in an organic matrix;
- and
- detecting through an optically detectable signal the binding of the fluoride ions to the lipophilic aluminum compound.
