Iodometry is a technique used widely in a number of fields to quantify peroxide contents. It’s been known that olefins may react with the molecular iodine intermediate generated in the process of iodometry. Using detailed laboratory measurements and a kinetic box model, our study for the first time studied this matrix effect systematically. We found that this matrix effect is negligible for outdoor aerosol, but can be significant for indoor materials, as well as edible oils.
