Abstract

Carbon paste electrodes, modified with podands containing more than two sulfur atoms, have been employed for the voltammetric determination of Ag(I) ion from aqueous solution. The voltammetric response was characterized with respect to paste composition, preconcentration method, kind of anion, variation of pH, Ag(I) ion concentration, and possible interferences. Linear calibration curves were obtained for Ag(I) ion concentration ranging from <TEX>$1.0{\times}10^{-6}$</TEX> to <TEX>$9.0{\times}10^{-5}M$</TEX>, and detection limit was <TEX>$5.0{\times}10^{-7}M$</TEX>.
