✦ Synopsis

Silver is deposited electrolytically on carbon fibers from acetate buffer at pH 4 .6 in the potential range from -0 .3 to -0 .8 V vs. SCE . Chronoamperometric and cyclic voltammetric measurements confirm that the mechanism of deposition is nucleation ; the rate is higher than that at large circular glassy carbon electrodes . The silver deposits are more stable, especially with respect to oxidation by air, than are similar deposits of mercury . Preliminary results on codeposition of silver and mercury are reported .
