| Abstract | A new electrode, obtained by the dispersion of ordered mesoporous carbon (MC) nanoparticles onto polyaniline (PANI) was presented in this paper. Ordered mesoporous carbon was prepared by pyrolysis of sucrose filled in the mesoporous channels of SBA-15 at 1 200 degrees C, and followed by dissolution of the silica matrix in hydrofluoric acid. The pore structure of the MC material, was evaluated using XRD, nitrogen adsorption, TEM. SEM showed that PANI-MC films presented a wholy modified morphology when compared to PANI film. Electrochemical characterization indicated that the potential shift toward negative direction. This can be attributed to the porous feature of MC, which imposes resistance for ion migration in mesoporous. The deposition potential and time had been optimized for determination of Cu2+ in aqueous solution. ASV analysis revealed that the new electrode presented a linear response to low concentrations of Cu2+. Under optimized conditions, the current showed a linear dependence with concentration in the range 1.00x10(-8)similar to 1x10(-6) mol . L-1. The detection limit was 6x10(-9) mol . L-1. The results showed good reproducibility and stability. |
