Status of Hydrogen Peroxide Solution 10 V in Commercialized Samples

de Menezes MN, Kogawa AC* and Salgado HRN

Hydrogen peroxide (H2O2) is one of the most powerful oxidants used in many sectors. Analytical method such as titration by permanganometry is used to maintain the quality of products containing H2O2. Thus, the objective of this work was to evaluate commercial samples of H2O2 10 V by permanganometry. A difference of almost 3 volumes was found in the analysis of the samples. These results can be real or assigned to the potassium permanganate solution, not automation of the results and/or instability of the H2O2 solutions, for example. The main issue is, in addition to alerting the consumers to adequate storage of H2O2 solutions, to alert the scientific community to the need for concomitant analysis methods for unstable products such as H2O2 10 V solutions in order to avoid doubts on the results and make the manufacturers aware of these quality tests.
