| 摘 要： | 在鼓泡反应器中研究了二氧化硫和硫化氢在三种不同pH值溶液,即水溶液、盐酸-柠檬酸钠缓冲溶液和碳酸钠-碳酸氢钠缓冲溶液中的反应行为.结果表明,液相中两者的反应主要是发生在硫化氢分子和亚硫酸氢根离子之间.在对实验数据分析的基础上,得出了三种液相溶液中的统一反应速率方程为r=kcH2SC0.5HSO3-,k=1.531×104exp(-2139—T)其中,反应活化能为17.78kJ·mol-1.

| Abstract: | The reaction behaviors of H2S and SO2 in three different pH solutions (water, buffer solution of chlorhydric acid-sodium citrate and buffer solution of sodium carbonate-sodium bicarbonate) were studied through a bubble reactor. The results indicate that reaction mainly happens between H2S and HSO3-. On the basis of experimental data, the reaction kinetic equation of H2S and SO2 in liquid phase for three different pH solutions was obtained as follows: -230.5HSHSOrkCC=, where 421391.53110exp()kT=?, the activity energy in this reaction is 17.78 kJmol-1. |
