摘　　要：本文提出一种静止液气液反应器与脉冲应答技术相结合测定气液反应速率常数的方法，导出了反应速率常数与气相反应组分转化率的关系式．测定了ＣＯ２在ＯＣｌ－催化下与碳酸盐缓冲溶液的拟一级反应速率常数值．结果表明，本方法具有测定简便、快速，结果准确的特点．A method based on the combination of quiescent liquid reactor and pulse-re- sponse technique is presented for determining the reaction rate constants of the gas-liquid re- actions. The relation between the reaction rate constant and the conversion fraction of gas reagent is derived. The pesudo-first order reaction constants of the reaction between CO2 and Na2CO3-NaHCO3 buffer solution catalysted by OCl- determined. Results show that the advantages possessed by the method are simple in experiment procedure, accurate in results.
