Hydrogen Peroxide Test Kits-CHEM A-5500

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. 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 will interfere. Results are expressed as ppm (mg/L) H2O2. The DDPD Method: With the DDPD Method, hydrogen peroxide reacts with DDPD in the presence of ammonium molybdate to form a purple 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.
