Loss of ozone on sulfate and sulfide doped-ice surfaces

The sticking coefficients of ozone on ice surface and solid solution of sulfate and sulfide were measured over a temperature range from 200K to 260K. Experiments were performed in a horizontal flow tube. Results indicate that the sticking coefficients of ozone on ice are in the range from 1.3x10^-7 to 2.7x10^-6, and it will become larger as temperature increases; the sticking coefficients of ozone on eight kinds of 0.1mol/L sulfate doped ice are in the range from 1.8x10^-7 to 6.9x10^-6; the sticking coefficients of ozone on four kinds of 0.1 mol/L sulfide doped ice are in the range from 3.2x10^-7 to 2.1x10^-5. Ozone loss on these particles was evaluated.
