The sticking coefficients of ozone on ice and doped ice

MU Yujing,LIU Ye,YANG Wenxiang\ (Research Center for Eco Enviromental Sciences Chinese Academy of Science,Beijing 100085)  
By flow reactor the sticking coefficients of ozone on ice and doped ice surfaces were measured over the temperature range from 220K to 260K. The results indicate: the sticking coefficients of ozone on ice is in the range from 1.3×10 -7 to 2.7×10 -6 , and increases with temperature ; the sticking coefficients of ozone on (NH 4) 2SO 4 and (NH 4) 2SO 3 doped ice surfaces show nonlinear relationship with the concentrations of (NH 4) 2SO 4 and (NH 4) 2SO 3; the residual life time of ozone on ice estimated by the experimental data is about 56 days, the loss of ozone on particles mainly composed water cannot be ignored.
