摘要：

Significant gas phase bromine enrichment is experimentally verified on flowing gaseous HOBr over ice surfaces doped with sodium halides of sea salt composition. It is argued that formation of Br2Cl- in the condensed phase followed by its dissociation with release of Br-2 into the gas phase accounts for this phenomenon.
