【摘要】 研究了在25℃时,S(IV)在模拟雨水中催化氧化反应级数以及反应速率常数随催化剂种类及浓度变化的关系;比较了空气与氧气对催化反应的影响;考虑了钒的催化问题。结果表明:在正常的大气浓度下,空气与氧气对催化反应的效果无明显差别,它们的浓度变化对反应速率无影响;钒对液相氧化无催化作用,但直接氧化作用不可忽视。更多还原

【Abstract】 The reaction order of S(IV) catalytic oxidation in test solution at 25C were studied. The reaction rate is connected with the kinds of catalysts and its concentration. Iri the experiments, the air was compared with oxygen for the effect, concluding the catalysts of Vanadium. It was indicated that in the atmosphere concentration, the effect on the catalytic oxidation between air and oxygen had no obvious difference. The changing of concentration of air and no oxygen had no effect on the reaction rate. Vanadium has no catalytic effect, but the direct oxidation cannot be neglected.更多还原
