Methods
Hydrogen peroxide is a strong oxidizing agent with a variety of uses. Applicati*** include the treating of industrial effluents and domestic waste and serving as a disinfectant in aseptic packaging.
For the food and beverage industry, CHEMetrics Hydrogen Peroxide CHEMets® and Vacu-vials® products are used extensively to monitor sterilization soluti*** in the packaging and sanitizing processes.
The Ferric Thiocyanate Method
Reference: D. F. Boltz and J. A. Howell, eds., Colorimetric Determination of Nonmetals, 2nd. ed., Vol. 8, p. 304 (1978).
The ferric thiocyanate method c***ists of ammonium thiocyanate and ferrous iron in acid solution. Hydrogen peroxide oxidizes ferrous iron to the ferric state, resulting in the formation of a red thiocyanate complex. Chlorine will not interfere with this method. Ferric iron and peracetic acid will interfere. Results are expressed as ppm (mg/L) H2O2.

The DPD Method
References: USEPA Methods for Chemical Analysis of Waters and Wastes, Method 330.5 (1983). APHA Standard Methods, 23rd ed., Method 4500-Cl G-2000. D.F. Boltz and J.A. Howell, eds., Colorimetric Determination of Nonmetals 2nd ed., Vol. 8, p. 303 (1978).
With the DPD Method, hydrogen peroxide reacts with DPD (N, N-diethyl-p-phenylenediamine) in the presence of potassium iodide and ammonium molybdate to form a pink color. Various oxidizing agents such as halogens, ozone, and peracetic acid will produce high test results. Results are expressed as ppm (mg/L) H2O2.
The Ceric Sulfate Titrimetric Method
Reference: Developed by CHEMetrics, Inc.
CHEMetrics developed a titrimetric method using ceric sulfate as the titrant and ferroin as the end point indicator. A color change from green to orange signals the end of the titration. Results are expressed as percent (%) H2O2. The test range can be modified by performing a sample dilution. Details are provided in the kit instructi*** for ranges of 0.01 – 0.1% through 2- 20%.
