英文摘要Understanding the photochemical reaction process between VOCs and co-pollutants in the troposphere is crucial for controlling the haze. The photochemical reactions of 1,3-butadiene (1,3-BD) with NO were carried out at 308 K for up to 96 h in clean air with various relative humidity (RH) values, and actual haze atmosphere. In the haze, the representative pseudo-first-order kinetic rate constants of the 1,3-BD-NO system was 1.53 time higher than those in dry clean air. The effect of the RH (0%-80%) on the conversion behavior of the 1,3-BD-NO system in clean air was studied, revealing that increasing RH promoted the photochemical reaction in the low range of 0%-40% but retarded it in the high range of 40%-80%. Interestingly, (OH)-O-center dot radicals were directly detected under different RH values, and the strongest (OH)-O-center dot signal was obtained at an RH of 40%. Multiple macromolecular products with carbon numbers of 10-36 were identified. Unexpectedly, richer products and extended unsaturation range were detected at an RH of 40% than 0%. The photochemical products were also analyzed using ion chromatography. A reaction mechanism was proposed from the detected NO2, O-3, (OH)-O-center dot, HNO2, HNO3, organic acids and macromolecular products. (C) 2020 Elsevier B.V. All rights reserved.
