摘要: 利用180-L Teflon气袋, 采用相对速率方法测定了298 K, 1.013×105 Pa条件下·OH自由基与6种还原态硫化物在空气、氮气和氧气体系下的反应速率常数. 所得结果与文献值进行了比较, 并讨论了氧气对速率常数的影响.

关键词: 速率常数, ·OH, 还原态硫化物

Abstract: The rate constants for the reactions between·OH and six reduced sulfur compounds in air, N2, and O2 were measured using relative rate constant method in a 180-L Teflon bag at 298 K and 1.013伊105 Pa. These results were compared with previous published data and were discussed in terms of trends in different buffer gases.

Key words: Rate constant, ·OH, Reduced sulfur compound
