Electrocatalytic oxidation of thiosulfate at 2,7-bis (ferrocenylethyl)-fluoren-9-one-modified carbon paste electrode (2,7-BFEFMCPE):Application to the catalytic determination of thiosulfate in real sample
摘要:
Electrocatalytic oxidation of thiosulfate at the 2, 7-BFEFMCPE occurs at a potential about 460 mV less positive than that unmodified carbon paste electrode. The diffusion coefficient (=5.6×10-5 cm2 s-1), the kinetic parameters such as electron transfer coefficient, (=0.5) and kh (=1.21×10-3 cm s-1) of thiosulfate oxidation at the surface of, 2, 7-BFEFMCPE were determined. The electrocatalytic oxidation peak current of thiosulfate showed two linear dynamic ranges (0.00 (0-0.009 mmol/L and 0.009-0.900 mmol/L) and a detection limit of 0.00015 mmol/L. This method was also examined as a new electrochemical sensor for the determination of thiosulfate in real sample.
