• Resumen

  • A suitable fow-injection method for the analysis of commercial solutions of hydrogen peroxide is described. A Nafon-coated glassy carbon electrode, modifed by deposition of copper hexacyanoferrate (CuCHF), is employed as an amperometric sensor. The method allows the analysis of 45 samples per hour, with peroxide concentrations in the range of 1.25 -10.0 mM, with relative standard deviations smaller than 1%.
