摘要

The HOBr and HOCl uptake coefficient γ on H2SO4-acidified submicron salt aerosol of known size distribution was measured in an atmospheric pressure laminar flow reactor. The interaction time of the trace gas with the aerosol was in the range 15 to 90 s and led to γ values in the range 10−4 to 10−2. The acidity of the aerosol is essential in order to enable heterogeneous reactions of HOBr on NaCl, recrystallized sea salt (RSS) and natural sea salt (NSS) aerosols. Specifically, HOCl only reacts on acidified NSS aerosol with a γ ranging from 0.4 × 10−3 to 1.8 × 10−3 at a relative humidity (rh) at 40 and 85%, respectively. Uptake experiments of HOBr on aqueous H2SO4 as well as on H2SO4-acidified NaCl, RSS or NSS aerosol were performed for rh ranging from 40 to 93%. The γ value of HOBr on acidified NSS reaches a maximum γ = 1.9 × 10−2 at rh = 76 ± 1% and significantly decreases with increasing rh in contrast to acidified NaCl and RSS aerosols whose γ values remain high at γ = (1.0 ± 0.2) × 10−2 at rh ≥ 80%. An explanation based on the formation of an organic coating on NSS aerosol with increasing rh is proposed.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
