H2O2 Determination by the I3- Method and by KMnO4. This protocol was developed to determine the tolerance of Pseudomonas aeruginosa biofilms to hydrogen peroxide (H2O2) killing. The bacteria are grown as colony biofilms on polycarbonate membranes, as previously described in Walters et al. 2003. The protocol may be adapted for other bacterial, with appropriate changes in H2O2 concentrations, Hydrogen peroxide (H 2 O 2), an important oxidizing agent (E 0 = 1.80 V), has been widely used for the removal of hazardous substances in the field of water treatment and soil remediation (Fang and Barcelona, 2003, Ksibi, 2006, Apul et al., 2016, Devi et al., 2016)..

Potassium permanganate reacts with hydrogen peroxide forming a colorless solution by the following reaction: KY 5 H202 + 2 KIn04 + 4 H2S04 - 2 KHS04 + 2 HnS04 + 502 + 8H20 This reaction is normally slow to begin. The presence of manganeous ions, however, acts as a catalyst and allows the titration to be done without delay. Objective: To determine the volume of KMnO4 needed for 4mL of H 2 S O 4 and the concentration of hydrogen peroxide. Background: Titration is a method of analysis which allow us to determine the precise endpoint of a reaction, and therefore, the precise quantity of reactant in the titration flask.
