We measured the first‐order loss rate coefficients for CF2O on solid surfaces, ice and HNO3‐treated ice, and on sulfuric acid solutions that coated the inside wall of a flow tube. We determined an upper limit for the uptake coefficient, γ, of ∼3×10−6 for CF2O on ice and HNO3‐treated ice. A value for γ on a 60% (by weight) sulfuric acid solution of 3(+2/−3)× 10−6 was measured and we observed a higher value over 40% acid, γ = 6×10−5 (± 30%). The loss of CF2O on stratospheric particles is a very slow process and will be insignificant for events that occur on timescales of a year, such as the annual polar chlorine activation phenomena.
