提出了一种快速、准确测定液相中ＣＯ２浓度的方法。考察了温度、Ｈ２ＳＯ４加入量等对结果的影响，并对该方法与其它分析方法作了对比及误差分析。结果表明：该方法操作简单、方便、精度高，尤其适用于液相中ＣＯ２低浓度的快速分析，具有推广应用价值。
A rapid and accurate method for the determination of CO2 concentration in liquid phase was proposed. The effects of temperature and H2SO4 loading on the results were investigated. The method was compared with other analytical methods and the error analysis was also made. The results show that the method is simple, convenient and accurate. It is especially suitable for rapid analysis of low concentration of CO2 in liquid phase and has the value of popularization and application.
