H2O2 Determination by the I3- Method and by KMnO4 Titration
TL;DR: The analysis of aqueous H 2 O 2 at concentrations as low as 1 μM is conveniently done by the I 3 - method, which is based on the spectrophotometric determination of I 3, formed when H 2 o 2 is added to a concentrated solution of I -. At 351 nm, E max (I 3 - ) was measured to be 26 450 M -1 cm -1.
