Abstract
The rate of absorption of carbon dioxide by solutions of NaHCO3, KH2PO4, hydrogencarbonate, phosphate and borate buffers at 20, 30 and 40 degrees C was determined manometrically. The absorption rate increases for all buffers tested with increasing pH. The CO2 absorption rate by KH2PO4 and by the phosphate buffer at low pH is lower than that of water. For other buffers tested it is equal to or higher than that of water, especially at higher temperatures.
摘要
通过压力计测定了在20℃、30℃和40℃下，NaHCO₃、KH₂PO₄、碳酸氢盐、磷酸盐和硼酸盐缓冲液对二氧化碳的吸收速率。对于所有测试的缓冲液，随着pH值的升高，吸收速率增加。在低pH值下，KH₂PO₄和磷酸盐缓冲液对二氧化碳的吸收速率低于水的吸收速率。对于其他测试的缓冲液，其吸收速率等于或高于水的吸收速率，尤其是在较高温度下。
