Abstract

The aim of this paper is to study the reaction products of alpha-pinene, beta-pinene, limonene, 3-carene and sabinene with OH radicals by FT-IR spectroscopy and by HPLC-MS-MS, to evaluate the secondary aerosol formation. All gas phase reaction products were quantified using reference compounds. As source of OH radicals were used H2O2 and CH3ONO. The experiments were performed at low terpene concentration (0.9-2.1 ppm) and at high terpene concentration (4.1-13.2 ppm), using H2O2 and CH3ONO as sources of OH radicals.

摘要

本文的目的是通过傅里叶变换红外光谱（FT-IR）和高效液相色谱-串联质谱（HPLC-MS-MS）研究α-蒎烯、β-蒎烯、柠檬烯、3-蒈烯和桧烯与羟基自由基的反应产物，以评估二次气溶胶的形成。所有气相反应产物均使用参考化合物进行定量。使用过氧化氢（H₂O₂）和亚硝酸甲酯（CH₃ONO）作为羟基自由基的来源。实验在低萜烯浓度（0.9 - 2.1 ppm）和高萜烯浓度（4.1 - 13.2 ppm）下进行，分别使用H₂O₂和CH₃ONO作为羟基自由基的来源。
