【摘要】 本文在F₄₆塑料薄膜反应袋中测定了臭氧与异戊二烯反应的速率常数k₁为1.32×10^-2ppm^-1min^-1。研究了异戊二烯存在时O₃对SO₂的氧化作用,发现在异戊二烯存在下,SO₂与臭氧氧化的速度明显增加。并讨论了在isoprene-O₃-SO₂体系中,SO₂的氧化机理,推导出SO₂的氧化速度与O₃、isoprene。SO₂的初始浓度之间的关系的表达式。更多还原

【Abstract】 The study of isoprene-O3-SO2 systems was performed in a 580-liter Teflon bag. The rate constant for the reaction of O3 with isoprene,k1, was determined to be 1.32×10-2ppm-1·min-1 The effect of O3 concentration on oxidation of SO2 were studied in the presence of isoprene. It was found that the rate of the SO2 oxidatiion by O3 increased obviously in the presence of isoprene. The SO2 oxidation mechanism in the isoprene-O3-SO2 systems was discussed and an expression of the relationship between SO2 oxidation rate and initial concentrations of O3, isoprene and SO2 was derived.更多还原
