Abstract

MATTOS, IVANILDO LUIZ DE; CAROLI, MARCOS; AREIAS, MADALENA  and  NAVARRO, MARCELO. A FAST, ROBUST ELECTROCHEMICAL METHOD FOR THE AUTOMATED DETERMINATION OF HYDROGEN PEROXIDE. J. Chil. Chem. Soc. [online]. 2009, vol.54, n.4, pp.414-416. ISSN 0717-9707.  http://dx.doi.org/10.4067/S0717-97072009000400020.

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%.

Keywords : Nafon-coated copper hexacyanoferrate modifed electrode; FIA system; Hydrogen peroxide quantifcation.
