Potentiometric flow injection analysis of concentrated hydrogen peroxide by using an Fe(II)-Fe(III) redox potential buffer solution.
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 approximately 10 M was conducted successfully with relative standard deviation of 0.7%.
