CHEMetrics Hydrogen Peroxide Kits
Hydrogen peroxide is a strong oxidizing agent with a variety of uses. Applications 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 solutions in the packaging and sanitizing processes.
The Ferric Thiocyanate Method
The ferric thiocyanate method consists 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, peracetic acid, and cupric copper will interfere. Results are expressed as ppm (mg/L) H2O2.
The DPD Method
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 product. Results are expressed as ppm (mg/L) H2O2.
The Ceric Sulfate Titrimetric Method
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 instructions for ranges of 0.01-0.1% through 2-20%.
