Electrochemical Oxidation of 2,5-Dimercapto-1,3,4-thiadiazole on Carbon Electrodes Modified with Ru(III) Schiff Base Complex

The thiol compound 2,5-dimercapto-1,3,4-thiadiazole is a potential cathode material. redox reactions of the mentioned are slow at room temperature but can be enhanced using electron transfer mediators. electrochemical oxidation on surface carbon electrodes modified with Ruthenium(III) Schiff base complex was studied by voltammetric methods and amperometric flow injection analysis. electrocatalytic properties glassy screen printed addition multi-walled nanotubes Nafion. Voltammetric studies showed that anodic DMcT electrode occurs +0.28 V vs. Ag/AgCl in Britton-Robinson buffer (pH 6.50). Flow measurements were performed +0.20 solutions pH 6.50 0.40 cm3 min–1 rate. results for had lower value detection limit (0.38 mg dm–3) quantification (1.28 dm–3), linear dynamic range from 1 to 500 dm–3 2,5-dimercapto-1,3,4-thiadiazole. Modified provided up 750 3.90 13.20 dm–3.
