| Abstract: | With Fe(CN)~(3-/4-)-6 ion as probe molecule,cyclic voltammetric technique was used to investigate the self-assembled monolayers(SAMs) of cysteamine.The electrochemical behavior of modified electrode was studied in Fe(CN)~(3-/4-)-6 solution of different pH.The surface pK-b of the self-assembled monolayers of cysteamine was obtained by the electrochemical titration method. |
