摘要
通过湿壁塔对高分子水溶液吸收ＣＯ２速率的测定，发现只有控制气液两相无因次接触时间ｔ＜０．１为判据时，依据渗透论测定计算出的扩散系数才能确保足够的精确性。
A wetted column was used to measure the rate of absorption of carbon dioxide in aqueous polymer solutions.The experimental results showed that the exactitude in diffusivity calculation by Higbie′s penetration theory can be ensured when dimensionless contact time t<0.1.
