Electroanalytical Study of Prussian Blue Modified Glassy Carbon Paste Electrodes [PDF]
Electroanalysis, 2003 AbstractTwo types of glassy carbon (GC) powder (i.e., Sigradur K and Sigradur G) have been mixed with mineral oil to obtain glassy carbon paste electrodes (GCPE's). The electrochemical behavior of such electrodes at different percentages of glassy carbon has been evaluated with respect to the electrochemistry of ferricyanide as revealed with cyclic ...
