摘要: An electrochemical technique is presented to simultaneously determine the concentrations of Fe(II) and Fe(III) ions using a rotating disk electrode. The method consists steady state polarization where developed limiting currents are measured related concentration cations present in solution. Two linear equations were derived which correlate with pair cations. used easily multivalent species. precision accuracy found be comparable other advanced methods for quantification cations, such as capillary zone electrophoresis spectro-photometric sequential injection analysis.
