چکیده:

The present work describes the construction of a new tin hexacyanoferrate (SnHCF) modified carbon ceramic electrode (CCE) by electrochemical procedure for the first time. The electrochemical behavior of the resulting modified electrode was investigated by cyclic voltammetry. The SnHCF modified CCE exhibited an excellent electrocatalytic activity toward the oxidation of phenylhydrazine at a reduced over potential. Limit of detection was found to be ٠٫٨٣ μM by chronoamperometric method. In addition the proposed sensor exhibited the advantages of simple preparation, fastresponse, good stability and reproducibility for phenylhydrazine determination.
