Abstract
With the development of a novel microfluidic system for environmentally friendly electrochemical pro-duction of hydrogen peroxide, a need for a specifically designed electrochemical sensor for hydrogen peroxide in alkaline media (pH 13) arises. Flash graphene was used to modify the carbon screen-printed electrode together with manganese dioxide. The proposed sensor exhibited two linear ranges (1 to 100 μmolL–1, and 100 to 1000 μmolL–1), the sensitivity of 0.244 μAμM–1cm–2 and the limit of de-tection was 0.238 μmolL–1.
