Determination of Sulfide by Hematoxylin Multi Walled Carbon Nanotubes Modified Carbon Paste Electrode
Original language description
This study investigates a new approach for the amperometric determination of sulfide using a hematoxylin multiwalled carbon nanotubes modified carbon paste electrode (HM-MWCNTs/CPE). The experimental results show that HM-MWCNTs/CPE significantly enhancesthe electrocatalytic activity towards sulfide oxidation. Cyclic voltammetric studies show that the peak potential of sulfide shifted from +400mV at unmodified CPE to +175mV at HM-MWCNTs/CPE. The currents obtained from amperometric measurements at optimum conditions were linearly correlated with the concentration of sulfide. The calibration curve was obtained for sulfide concentrations in the range of 0.5-150x10(-6)molL(-1). The detection limit was found to be 0.2x10(-6)molL(-1) for the amperometric method. The proposed method was successfully applied to a river water sample in Pardubice, Czech Republic.
