柠檬酸缓冲溶液吸收低浓度SO_2动力学研究

The Study on Absorption of Dilute SO_2 in Citric Acid Buffur Solution

本文采用具有平稳气液接触面的双磁力驱动微分搅拌反应器,进行了柠檬酸缓冲溶液对低浓度SO_2气体的吸收实验。分别研究了气相浓度、溶液特性、液相搅拌速率对SO_2吸收速率的影响。提出该吸收过程的理论模型,由此推导出数学模型,并通过实验证明了模型的合理性。

Absorption of dilute SO_2 in citric acid buffur solutions has been tested by using a differential stirred vessel with a flat gas-liquld interface driven by double magnets. The effects of the concentration of SO_2 in gas phase, solution characteristics and stirred speed on the absorption rate have been investigated. Theoretical models for the absorption process have been developed and mathematics models are also given. By comparing theoretical calculations with experimental results, those models have been proved feasible.
