Studies on quenching of fluorescence of reagents in aqueous solution leading to an optical chloride-ion sensor
نویسندگان
چکیده
The sensitivity of quinolineand acridine-type indicators towards the detection of low levels of chloride ions in aqueous and amine-doped media, by fluorescence quenching, is reported in this paper. Solution studies are based on the fluorescence of quinine sulphate, acridine and 3(6-methoxyquinolino) propanesulphonate (SPQ) and the fluorescence response of these indicators has been examined at different pH values and at various chloride ion concentrations in aqueous media.

The fluorescence Quenching Study of Quinine in Presence of Some Anions
The quenching of quinine fluorescence intensity in the presence of some anions in aqueous solution at ambient temperature has been investigated. The quenching is found to be collisional or dynamical in nature. This study reveals the order of two groups of quencher: NaI > NaBr > NaCl > NaF and K2Cr2O7 > KMnO4 >Na2SO4 > NaClO3. Increasing anion size in the both groups leads to an increase in the...
متن کاملComparison of new optical sensor based on triazene ligand immobilized on PVC and triacetylcellulose membranes for Hg (II) Ion
For spectrophotometric analysis of Hg (II) ions, we have used and compared two membranes preparation methods using different polymer; one is poly(vinyl chloride) (PVC) and the other is triacetylcellulose (TAC). In the case of TAC membrane, it was treated with a ligand solution (1.166 × 10-3 mole L-1) in ethylenediamine at the ambient temperature for almost 2-5 min. However, in the case of PVC m...
متن کاملFibre optic chloride sensor based on fluorescence quenching of an acridinium dye
In this paper, research into the fabrication and characterization of a new fibre optic sensor for chloride ion detection is reported. This sensor is based on the fluorescence quenching of an acridinium dye, which is covalently bound to polymer substrates, in presence of chloride ions. The active material is formed as a powder and packed in a tablet form. Calibration data shows that this fibre o...

Tin(II)-ion-selective electrode consisting of dibenzo-18-crown-6 (DB18C6) as an ionophore inPVC matrix was developed. The influences of membrane composition, selectivity, response time,reversibility and temperature on the electrode performance were investigated. The electrodeshowed a near Nernstian response for Sn2+ ions over a concentration range from 1.0× 10-6 – 1.0× 10-2 M with a slope of 27...
