英文摘要 | Seed particles Al2O3, Al-2(SO4)(3) and H2SO4 were selected to investigate their effects on secondary aerosol (SA) formation in toluene/NOx photooxidation under sulfur dioxide (SO2) and ammonia (NH3). Effect of seed particles on SA formation was related to their acid-base properties and the presence of acid or alkaline gases. Under NH3-poor condition, SA formation increased with increasing SO2 concentration due to the acid-catalyzing effect of the oxidation products of SO2 (i.e. H2SO4). The enhancing effect of SO2 became unobvious under NH3-rich condition, because NH3 would eliminate the acid-catalyzing effect by neutralizing the acid products. Acidic seeds H2SO4 accelerated SA formation under either SO2 or NH3 condition. Weak acidic Al-2(SO4)(3) seeds didn't affect obviously on SA formation. The inhibiting effect of amphoteric seeds Al2O3 on SA formation was related to the presence of SO2 / NH3 due to their acid-base property. Under NH3-poor condition, the inhibiting effect of Al2O3 on SA formation decreased with increasing concentration of SO2, while under NH3-rich condition, the inhibiting effect wasn't remarkable.
