Analysis of hydrogen peroxide

Discussion. Hydrogen peroxide reacts with iodide in acid solution in accordance with the equation

The earliest examples of analytical methods based on chemical kinetics, which date from the late nineteenth century, took advantage of the catalytic activity of enzymes. Typically, the enzyme was added to a solution containing a suitable substrate, and the reaction between the two was monitored for a fixed time. The enzyme s activity was determined by measuring the amount of substrate that had reacted. Enzymes also were used in procedures for the quantitative analysis of hydrogen peroxide and carbohydrates. The application of catalytic reactions continued in the first half of the twentieth century, and developments included the use of nonenzymatic catalysts, noncatalytic reactions, and differences in reaction rates when analyzing samples with several analytes.

Thus, if a putative radical scavenger is incubated with hydrogen peroxide and the reaction mixture sampled for analysis of hydrogen peroxide at various times, the rates of loss of hydrogen peroxide can be measured to allow calculation of rate constants.
