Abstract

USUALLY ALL ELECTROCATALYTIC STUDIES HAVE BEEN PERFORMED WITH METALS SUCH AS AU, AG, NI, PT OR THEIR ORGANOMETALLIC COMPOUNDS. IN THIS CASE, SMALLER ATTENTION HAS BEEN FOCUSED ON COPPER OR COOPER COMPOUNDS. IN FIRST STEP OF THE PRESENT WORK, NANOPARTICLES OF CUWO4 WERE PREPARED VIA A SIMPLE PROCEDURE AND IN THE NEXT STEP, THE ELECTROCHEMICAL BEHAVIOR OF CUWO4 WAS EVALUATED IN BUFFER SOLUTIONS USING CYCLIC VOLTAMMETRIC TECHNIQUE. THE OBTAINED RESULTS SHOWED THAT THIS ELECTRODE ENHANCE THE ELECTROCATALYTIC OXIDATION OF TRYPTOPHAN WITH REDUCTION OF OVERPOTENTIAL ABOUT 200 MV. THE MORPHOLOGY AND CHARACTERISTICS OF CUWO4 WERE INVESTIGATED BY FT-IR, XRD AND SEM. THE OPTIMUM CONDITIONS FOR CONSTRUCTION OF A NEW CARBON PASTE ELECTRODE USING CUWO4 FOR DETECTION OF TRYPTOPHAN WERE OBTAINED. THE PROPOSED ELECTRODE WAS USED FOR THE DETERMINATION OF TRYPTOPHAN IN PHOSPHATE BUFFER SOLUTION (0.1 M, PH 7) AT CONCENTRATION RANGE OF 0.1-10 MM THROUGH DIFFERENTIAL PULS VOLTAMMETRIC AND AMPEROMETRIC METHODS. THE PROPOSED ELECTRODE WAS SUCCESSFULLY USED FOR THE DETERMINATION OF TRYPTOPHAN IN BIOLOGICAL SAMPLES.
