چکیده:

aminopropyl-grafted MCM-41 was prepared and characterized with XRD method .then this material was
used for preparation of a modified Carbon paste electrode .Results show that electrochemical pretreatment of
this modified carbon paste electrode in acidic solution increased the absorbance of ferrocyanide to the
electrode surface. we used this electrode for open circuit accumulation and voltmmetric determination of
ferrocyanide in aqueous solution, and investigate factors affecting magnitude of analytical signal. under
optimum condition this electrode was successfully used for detection of ferrocyanide as an anionic
electroactive species and a linear response in the concentration range of 2 ×۱۰-۷ – ۱×۱۰-۵ M was observed.
