Frequent handwashing using water and soap and stringent use of disinfectants are fundamental in the ongoing fight to curb the spreading of the Corona virus. Metrohm has published Application Notes detailing titration methods for manufacturers of disinfectants to help determine the concentration of key components in their product.
Hydrogen peroxide content as per ASTM D2180
Peroxides are used for disinfection and water treatment purposes due to their antiseptic properties. Peroxides, perborates, and percarbonates can be easily determined by titration. The Application Note describes two titration methods for peroxide analysis: ASTM D2180 for concentrated hydrogen peroxide solutions, and a second method for trace determination of hydrogen peroxide, suitable for concentrations as low as 0.4 mg/L.
Hypochlorite and sodium chloride in disinfectant
This Application Note describes a reliable method to determine the hypochlorite and sodium chloride content in disinfectants by two subsequent argentometric titrations in the concentration range recommended by the WHO (1000 mg/L to 5000 mg/L NaOCL, 200 g/L NaCl).
