Abstract :
The flow injection analysis of hydrogen peroxide is proposed, using a redox electrode and an Fe(II)–Fe(III) potential buffer solution. Influencing factors, such as the concentrations of Fe(II)–Fe(III) and sulfuric acid in the potential buffer on sensitivity of the proposed method are examined. The analysis of high concentrations of hydrogen peroxide up to ∼10 M was conducted successfully with relative standard deviation of 0.7%.
