| 摘 要： | 以Na2CO3和NaHCO3的混合液作为用碱液吸收CO2气体的模拟液,用两室单阴膜电渗析装置对其在小于5V的低电压下进行脱碳处理,并且得出电渗析的方法可以增加回收液中Na2CO3和NaHCO3的浓度比,减少碳的总浓度,起到了对CO2的碱吸收液再生利用的作用。

| Abstract: | An electrodialysis(ED) reactor with anion-selective membrane is employed to recovery the base solution which had absorbed CO_2 under low voltage.In this experiment,the mixed solution of Na_2CO_3 and NaHCO_3 is used to simulate the base solution.The results of the experiments are presented and discussed.Moreover,the results indicate that electrodialysis can raise the ratio of the concentration between Na_2CO_3 and NaHCO_3 and reduce the total concentration of carbon in the solution.The base absorbent solution can be recovered through this process. |
