Abstract

The photooxidation of 1, 3-butadiene ( C4H6 ) was simulated using a self-made smog chamber. The gas phase products of C4H6 ozone oxidation reaction were detected by an on-line Fourier transform infrared gas analyzer. The results show that gas-phase products have CO, formaldehyde and acrolein, and compared with FACSIMILE software simulation results. The effects of seed aerosol on the formation of secondary organic aerosol( SOA ) by C4H6 photooxidation were investigated. It show that sodium silicate seed aerosol obstructs the generation of SOA, and its concentration has influence on the strength of the obstacles; Calcium chloride, ammonium sulfate and ammonium nitrate seed aerosols also obstruct the generation of SOA, but the effect of the concentration is not obvious; The order of four kinds of seed aerosol obstruct the generation of SOA is ammonium nitrate> sodium silicate> calcium chloride and ammonium sulfate.

Key words： 1, 3-butadiene smog chamber secondary organic aerosol seed aerosol
