英文摘要	A challenge for understanding the environmental fate of atmospheric organic acids is to evaluate the impacts of their heterogeneous interactions with mineral dust aerosols in the atmosphere. However, the uptake of organic acids on authentic natural mineral dust is rarely investigated under atmosphere-relevant conditions. Herein, we investigated the uptake of acetic acid (AcA) onto a natural mineral dust from the Gobi Desert, Gobi dust, under atmosphere-relevant conditions, combining both the gas-phase and adsorbed-phase approaches. Gobi dust is evidenced to reversibly and irreversibly adsorb AcA molecules under both dry and humid conditions. In the presence of moisture, the fraction of the reversibly adsorbed AcA is promoted, which addresses the impact of water molecules with AcA on minerals. Physisorbed AcA monomer, dimer, and chemisorbed acetate are identified based on real-time surface monitoring using diffuse reflectance infrared Fourier transform spectroscopy. This study provides original data and insights into the impacts of heterogeneous interactions with mineral dust on the environmental fate of acetic acid. It also provides complete and visual mechanisms for a comprehensive understanding of the involved surface reactions. This study initiates the exploration of the heterogeneous kinetics of the fractions of reversibly and irreversibly adsorbed AcA on natural mineral dust under atmospheric conditions.
