碳酸盐缓冲溶液吸收CO_2反应活化能的脉冲响应法测定

Determination of Activation Energy of CO_2 Absorption in Carbonate Bicarbonate Buffer Solution by Pulse-Response Method

在气相色谱仪上配置计算机数据采集处理机的装置内，以作者建立的脉冲响应技术测定 了 ２５～３３．５℃温度范围内碳酸盐缓冲溶液吸收 ＣＯ２时反应的活化能 Ｅ，测定值 Ｅ＝６９．７ｋＪ／ｍｏｌ， 表明该方法和相应装置可以分辨３至５度的温度差别．

The determination was carried out at 25-33.5℃ with the Pulse-Response method proposed by the authors in the gas chromatograph-based apparatus previously established and equipped with computerized data acquisition system. The obtained value of activation energy, E = 69.7kJ / mol, was in fairly good agreement with the published data. The results show that the apparatus was able to respond to a difference in temperature of from 3 to 5 de-grees.
