Fluorescent materials are some kind of reagents with vast applications in sensors. Considering the importance of the deremination of sulfate ion in environmental, chemical, pharaceuticals and food samples, in this research we used the fluorescence properties of 2,6-diphenyl-pyrylium tetrafluoroborate (DPF) for the design and construction of an optical sensor for the determination of SO42- ions. The results showed that the fluorescence intensity of DPF quenched upon the addition of sulfate ions, which was proportional to the sulfate concentration. Effective parameters were optimized and under optimal conditions the proposed optode was successfully applied to the determination of sulfate content in a drug sample.
