Influence of the heterogeneous reaction HCl + HOCl on an ozone hole model with hydrocarbon additions
Injection of ethane or propane has been suggested as a means for reducing ozone loss within the Antarctic vortex because alkanes can convert active chlorine radicals into hydrochloric acid. In kinetic models of vortex chemistry including as heterogeneous processes only the hydrolysis and HCl reactio...
