摘要
The electrochemical behavior of a ruthenium-modified cobalt每hexacyanoferrate electrode grown electrochemically onto a gold surface previously coated with a monolayer of 3-Mercaptopropionic is reported. Studies on the incorporation of ruthenium centers into the hexacyanoferrate layer were performed and the procedure represented a very effective contribution to the maintenance of the electrode stability. The film exhibited sharp redox peaks at about 0.5V in the presence of K+ and the peak potential shifted linearly with K+ concentration over the range 1.0 mmol L-1 to 1.0 mol L-1.
