Abstract
The destruction of ozone on ice surfaces was studied with;tn ice-coated fus ed silica column used as a very long flow tube. Ozone destruction was found to be very slow. At :223 K and 258 K the measured reaction probabilities f all in the range 2 x 10(-8) - 4 x 10(-10), decreasing with increasing ozone concentration (20 - 1000 nbar). The observed kinetics are explained by an at least two step mechanism. The bn reaction rates observed are insignifica nt for ozone destruction in cirrus clouds.
