英文摘要	The heterogeneous uptake of formic acid and acetic acid on mineral dust and coal fly ash was investigated using Knudsen cell reactor over the temperature range from 263 to 298 K. The uptake of formic acid and acetic acid on Inner Mongolia desert, Arizona test dust, and coal fly ash was mainly physical adsorption, while the uptake process on Xinjiang sierozem was the combination of physical adsorption and chemical adsorption as it contained a considerable amount of calcite. Uptake coefficients of formic acid and acetic acid on mineral dust increased with the content of element Si, aluminosilicate, and/or quartz in mineralogy, but the uptake coefficients on coal fly ash were smaller than that on mineral dust, which was controlled by the chemical components and microstructure. Compared with formic acid, uptake coefficients of acetic acid were higher on mineral dust and coal fly ash, especially in the low temperature regions. The atmospheric implications of formic acid and acetic acid on mineral dust aerosols are also discussed.
