Although European law demands emission control for SO2F2, this currently has little practical consequence, due to a lack of feasible separation methods for SO2F2 from air. An evaluation of the state-of-the-art shows that gas adsorption has a high potential to be practically implemented to mitigate SO2F2 emissions from fumigation. In a screening of different commercial adsorbents, the activated carbon Air CC 816 and the zeolite HiSiv 3000 indicated promising adsorption capacities for SO2F2, in dry and humid air. Thereby, this study presents the first comprehensive screening of commercial adsorbents for SO2F2 recovery in general and the first report on SO2F2 adsorption on activated carbons and zeolites under humid conditions. Air CC 816 and HiSiv 3000 appear to primarily adsorb SO2F2 physically, allowing a recovery for possible reuse and omitting catalytic decomposition of SO2F2. For the zeolite HiSiv 3000, SO2F2 isotherms and mass transfer kinetics are measured and used to derive the adsorption enthalpy. On this zeolite, water and SO2F2 exhibit co-adsorption behaviour where water displaces SO2F2. Based on experimental characterization, a concept for an adsorptive recovery on HiSiv 3000 is designed, suggesting the suitability of hot gas desorption with additional external heat input, or steam desorption, for SO2F2 recovery. Finally, a first field test for SO2F2 adsorption after container fumigation already showed promising breakthrough times on HiSiv 3000.en2213-343720256Elsevier BVhttps://creativecommons.org/licenses/by/4.0/Activated carbonAdsorptionFumigantRecoverySulfuryl FluorideHiSiv3000ZeoliteTechnology::628: Sanitary; MunicipalTechnology::660: Chemistry; Chemical EngineeringJournal Articlehttps://doi.org/10.15480/882.1615210.1016/j.jece.2025.11927010.15480/882.16152Journal Article
