Resumo: | In the present paper, the use of carbon paste electrode modified by carbon nanotubes and benzofuran derivative (1-(4-(1,3-dithiolan-2-yl)-6,7-dihydroxy-2-methyl-6,7-dihydrobenzofuran-3-yl) ethanone) for the electrocatalytic determination of isoproterenol (IP) was described. The charge transfer coefficient, α, and the charge transfer rate constant, k s, for electron transfer between the benzofuran derivative and the carbon paste electrode were calculated as 0.52 and 1.04 s-1, respectively. The anodic overpotential of IP is decreased about 256 mV by this modified electrode. Differential pulse voltammetric (DPV) peak currents of IP, acetaminophen (AC) and folic acid (FA) increased linearly with their concentration in the ranges of 0.05-2000.0 µmol L-1, 50.0-1200.0 µmol L-1 and 67.0-1600.0 µmol L-1, respectively and the detection limits for IP, AC and FA were 0.020 µmol L-1, 0.385 µmol L-1 and 0.690 µmol L-1, respectively. |
