“…The determination of halogen anion is important in many areas of everyday life, such as food [1], environmental monitoring [2], industrial applications [3,4], and clinical diagnosis [5][6][7][8][9]. These wide applications based on various areas produce a requirement for increased selectivity and sensitivity to detect the halogen anion.…”

“…Halide determination is important in many areas of everyday life, including foodstuffs, 1,2 industry, 3,4 and medicine. [5][6][7][8] Our particular interest in plastic halide sensors lies in their potential use in photographic processing equipment, where halide concentration is an important control parameter. Photographic processing is often carried out in mildly alkaline solutions, with halide concentrations Յ 0.1 mol dm Ϫ3 .…”

A range of halide-sensitive fluorophores were bound to two hydrophilic copolymers. Thin films of the copolymers swelled in the aqueous media, allowing dye fluorescence to be dynamically quenched by the diffusion of halide ions. The resultant sensor films were characterized in terms of their hydrophilicity, sensitivity, and selectivity toward halide. The sensor films were reversibly capable of determining aqueous bromide and iodide at a mildly alkaline pH with typical 90% response times of 30 -70 s and a shelf life in excess of 2 years.

“…However, relatively little attention has been paid to thin-film halide sensors [8][9][10]. This is quite surprising since halide determination is important in many areas of life, including medicine (human plasma [11] and urine [12]), food stuffs (cheeses [13] and wines [14]) and industry (nuclear materials [15], cements [16] and photographic emulsions [17] to name but a few).…”

A compact optical flow cell for use in aqueous halide determination has been developed. The performance of the cell and optical setup has been tested by studying the halide quenching of fluorescence from thin polymeric films containing a halide-sensitive fluorophore. Aqueous halide is injected into the flow cell and the quenched fluorescence emission observed orthogonal to the plane of excitation after it has undergone total internal reflection within the glass support-an efficient method for observing weak fluorescence intensities. The experimental setup is both a low-cost and an accurate method for use in the determination of aqueous halide ions. The method can very easily be adopted to determine other aqueous anions which quench the fluorescence of dyes incorporated into thin hydrophilic polymer films. The suitability of this method for the continuous measurement of halide 'on-line' rather than a single 'static' measurement is discussed.
