Abstract

A series of experiments were conducted in a self-made photochemical smog chamber, which was used to research the effect of light intensity and initial on the secondary organic aerosol ( SOA) production in the photochemical reactions of 1,3-butadiene(C4H6) and NO2 under room temperature of (297±2)K. The results show that the maximum concentration of SOA and the conversion rate of 1,3-butadiene are both increased with the increase of light intensity; the particle size and the number of SOA have a significant increase with the increase of the ratio of C4H6 to NO2 concentration of reactors ([C4H6]0/[NO2]0), and show a good linear relationship with the maximum concentration of the number of SOA. The main gas-phase products in the were determined by the Fourier transform infrared analyzer (FT-IR). are CO, CO2, carbon dioxide, acrolein and formaldehyde, etc.

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