Uptake is an initial step occurring in heterogeneous atmospheric reactions. It is a key step necessary to understand the reaction mechanism of heterogeneous reactions occurring on polar stratospheric clouds (PSCs) surfaces. The uptake of HBr on ice films has been investigated in a fast flow reactor and the amount is determined by using a differentially pumped quadrupole mass spectrometer combined with a pulsed molecular beam sampling method. A larger uptake and the formation of hydrobromic acid hydrates were observed in the uptake experiments. The effect of the ice film temperatures, HBr pressures, and ice film morphology on the uptake is studied. We will compare the uptake of HCl, HBr and HI on the basis of our recent studies. The results will lead to an advanced understanding of heterogeneous bromine reactions on PSCs.
