Abstract

 SULPHONAMIDES ARE SYNTHETIC ANTIBACTERIAL DRUGS WITH LOW POTENCY USED AGAINST A WIDE RANGE OF PARASITIC ORGANISMS INCLUDING PLASMODIA, TOXOPLASMA GONDII AND PNEUMOCYSTIS CARINII.THEIR MECHANISM OF ACTION IS BASED ON THE INHIBITION OF DIHYDROPTEROATE SYNTHETASE.SULPHONAMIDES ARE USED FOR THERAPEUTIC, PROPHYLACTIC AND GROWTH-PROMOTING PURPOSES IN ANIMALS AND IN THE TREATMENT OF TRACHOMA AND OCULAR TOXOPLASMOSIS IN OPHTHALMOLOGY [1]. IN THIS WORK, A SIMPLE AND RAPID ELECTROCHEMICAL METHOD WAS DEVELOPED FOR THE DETERMINATION OF SULFAMETHAZINE (SMT) AT A GLASSY CARBON ELECTRODE MODIFIED WITH MULTI WALLED CARBON NANOTUBE (MWCNT-GCE), USING CYCLIC VOLTAMMETRY. SMT SHOWED AN IRREVERSIBLE OXIDATION PEAK AT BARE ELECTRODE AT POTENTIAL OF 1.08V. WITH THIS MODIFIED ELECTRODE THE OXIDATION PEAK POTENTIAL OF SMT WAS SHIFTED ABOUT 0.12 V TOWARD A LESS POSITIVE VALUE, PRESENTING A PEAK CURRENT MUCH HIGHER THAN THOSE MEASURED ON AN UNMODIFIED GCE. UNDER THE OPTIMAL EXPERIMENTAL CONDITIONS THE PEAK CURRENT OF SMT WAS FOUND TO BE PROPORTIONAL TO ITS CONCETRATION OVER TWO LINEAR RANGES OF 10-200 MM AND 300-3000 MM [2]. THE KINETIC PARAMETERS SUCH AS THE ELECTRON TRANSFER COEFFICIENT BETWEEN SMT AND MODIFIED ELECTRODE, A, AND THE CHARGE TRANSFER RATE CONSTANT, KS, FOR OXIDATION OF SMT AT THE MWCNT–GCE SURFACE WERE DETERMINED ACCORDING TO THE LAVIRON PROCEDURE [1]. THE LIMIT OF DETECTION (LOD) WAS OBTAINED AS 6.15 MM. THE INFLUENCE OF POTENTIAL INTERFERING SUBSTANCES ON THE DETERMINATION OF SMT WAS EXAMINED. THE METHOD WAS SUCCESSFULLY APPLIED TO DETERMINATION OF SMT IN SERUM SAMPLE [2].
