含溴自由基对臭氧光解损耗的影响
AFFECTION OF BROMIDE RADICAL ON THE PHOTOSENSITIZED DECOMPOSITION OF OZONE
【摘要】 本文研究了253.7nm的紫外光照条件下臭氧的损耗,以及在有N2和O2的体系中臭氧损耗的状况,得到不同条件下臭氧损耗的量子产额,并进一步测定了在近似同温层条件下溴损耗臭氧的量子产额为24±1,计算出BrO+BrO反应的两个分支反应通道的速率比为5.25±0.26.
【Abstract】 In this paper, quantum yield for the photosensitized decomposition of ozone in the pure O3, O3+O2 and O3+N2 systems under the irradiation of 253. 7nm is studied. The quantum yield of the depletion ozone by brimide under the condition similiar to strato-sphere is further determinated, the ratio of two branches of BrO + BrO is 5. 25 + 0. 26.
