快速测定液相中CO2浓度的方法

Determining Carbon Dioxide in Liquid Quickly

文章阐述一种准确且快速测定液相中CO2浓度的方法,考查了温度,响应剂H2SO4及固定相Na3C6H5O7·2H2O的加入量对电位数的影响,并就该方法与其他分析法作了对比及误差分析。实验结果表明:此种方法操作简便,精度高,尤其适用于液相中低浓度CO2的快速测定及分析,具有普遍化的价值。

A method of accurately and quickly determining carbon dioxide in liquid is introduced.The effect of temperature,quantity of H2SO4 and Na3C6H5O7·2H2O on the results are investigated.The method is compared with others in error analysis.The results show that this method is convenient,highly accurate,especially can be used to determine and analysis carbon dioxide of concentration in liquid quickly.
