In this application H2O2 content is determined using redox titration methods using Cerium (IV) sulfate as the titrant and a DMi140-SC electrode.
Background
Hydrogen peroxide (H2O2) is a strong oxidant, known to be very effective against myriad of microorganisms along with bacteria, yeasts, fungi, viruses, and spores. A solution of 0.5% hydrogen peroxide solution generally referred as Hydrox shows combined microbial killing having a cleaning efficiency on medical devices that is better than many detergent solutions. 3% hydrogen peroxide is an effective and stable disinfectant when used on inanimate surfaces like soft contact lenses, tonometer biprisms, ventilators, fabrics, and endoscopes whereas concentrations from 6% to 25% act as chemical sterilants. However 0.125% hydrogen peroxide is used in preparation of handrub sanitizers.
METTLER TOLEDO provides an precise and automated method to determine the concentration of hydogen peroxide for determining its use as bleaching agents, disinfectants or sanitizers.
