英文摘要	Surfactant, which is ubiquitous in the atmosphere, has an important effect on the hygroscopicty of nanoscale atmospheric aerosol particles. However, the knowledge on the high relative humidity (RH) section (90–100%) is insufficient due to the limitation of traditional measuring instruments. In this study, the hygroscopicity of aerosol particles consisted of adipic acid (AA) and ammonium sulfate (AS) at RH = 80–99.5% was studied using the experimental and the theoretical method. The growth factor (GF) values at different RH were measured by the high humidity tandem differential mobility analyzer (HHTDMA). With some assumptions, a new model (Model 3 (UNIFAC)) accounting for the reduction of surface tension, the effect of the bulk-surface partitioning of AA and the non-ideal of solution on the particle hygroscopicity was established to describe the experimental results. An overall better performance is shown after comparing with six traditional models. Moreover, the partitioning of AA and the non-ideal of solution were investigated in details by comparing the outcomes of corresponding models. The comparisons between Model 2 (UNIFAC) and Model 3 (UNIFAC) and between Model 3 (Ideal) and Model 3 (UNIFAC) indicate that both the partitioning of AA and the non-ideal properties of solution in particles result in the decrease of GF. In addition, the change of water activity affected by these two dynamic processes acts as a more important factor than surface tension in the decrease of GF. Moreover, RH, the mass ratio and the initial diameter have significant impact on the AA partitioning, the non-ideal properties of solution and their influences on the hygroscopicity of particles. © 2021 Elsevier Ltd
