TY - JOUR ID - 483753 AU - Hasoň, Stanislav - Vetterl, Vladimír PY - 2002 TI - Application of carbon electrodes modified with a mercury layer of a different thickness for studies of the adsorption and kinetics of phase transients of cytidine. JF - Journal of Electroanalytical Chemistry VL - 536 IS - 1 SP - 19 EP - 19 PB - Elsevier SN - 00220728 KW - cytidine adlayers KW - two-dimensional condensation KW - nucleation and growth KW - mercury film electrodes KW - glassy carbon electrodes KW - pyrolytic graphite electrodes; N2 - The kinetics of phase transients of cytidine adsorbed at pyrolytic graphite electrodes, glassy caron electrodes, and the same electrodes modified with a mercury layer (mercury film electrodes)was studied by chronoamperometry (j-t curves and capacitance measurements (C-t curves). In acidic solution (pH 5) the two-dimensional condensation of adsorbed cytidine molecules and formation of a compact layer takes place only in one potential region. In alkaline solution (pH 8.3) cytidine forms two different physisorbed condensed layers at the mercury film electrodes. The phase trasients between the dilute and compact cytidine layers are about three times faster in acid solution than in alkaline solution. As long as the thickness of the mercury layer was greater than 2um, pronounced current maxima characteristic for the nucleation process were observed on j-t curves during phase transients between dilute and compact layers.
