摘要：

Mixed dodecanethiol-glutathinone self-assembled monolayers (DDT-GSH) were prepared on a gold electrode and further derivatized to form a monolayer of cupric hexacyanoferrate (CuHCF). Electrochemical behavior of the modified electrode was investigated by cyclic voltammetry. This inorganic monolayer modified electrode is electroactive and its surface concentration is 4.2 x 10(-10) mol cm(-2). Tt is observed that this modified electrode shows selectivity to potassium ion and exhibits an ideal Nernstian response with a slope of 60 mV/decade to potassium ions in the range from 10(-2) to 1.0 mol L-1.
