| 英文摘要 | In this study, the temperature dependence of the heterogeneous uptake of acrylic acid on Arizona test dust (ATD) has been investigated within a temperature range of 255-315 K using a Knudsen cell reactor. Combined with diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) experiment, it was found that acrylic acid could adsorb on ATD via surface OH groups and convert to carboxylate on the particle surface. The kinetics study suggests that the initial true uptake coefficient (gamma(t)) of acrylic acid on ATD decreases from (4.02 +/- 0.12) x 10(-5) to (1.73 +/- 0.05) x 10(-5) with a temperature increase from 255 to 315 K. According to the temperature dependence of uptake coefficients, the enthalpy (Delta H-obs) and entropy (Delta S-obs) of uptake processes were determined to be -(9.60 +/- 0.38) KJ/mol and -(121.55 +/- 1.33) J u K/mol, respectively. The activation energy for desorption (E-des) was calculated to be (14.57 +/- 0.60) KJ/mol. These results indicated that the heterogeneous uptake of acrylic acid on ATD surface was sensitive to temperature. The heterogeneous uptake on ATD could affect the concentration of acrylic acid in the atmosphere, especially at lowtemperature.
