Abstract

Several membrane-coated carbon rod anion-selective electrodes (CCRISE) were prepared by incorporating metal complex of bis(diphenylphosphino) propane (BDPPP) in a plasticized PVC film and their response characteristics were studied. Highly sensitive sensors were obtained with detection limit of 10^-7, 10^-6, 10^-5.5 and 10^-5.0M for ClO₄^-; SCN^- and I^-; Br^- and NO₃^-; Cl^- and benzoate (Bz^-) ions, respectively.
