Electrodialysis Metathesis (EDM) desalination was investigated using a squad of three ion-exchange membranes (ACS, TW-A, and A3) and simulated tobacco extract liquid for selective ions removal. We have studied various factors affecting EDM desalination efficiency using a complete experimental design. First, diffusion dialysis (DD) was conducted to determine the permeation rate of different anions in tobacco liquor with different membrane materials. We conclude that A3 had the fastest permeation rate of anions. However, ACS has the lowest permeation rate for different salts. The investigation of the EDM process showed the excellent ion permeation ability of A3 by detecting the current, conductivity, and ion concentration of the target tobacco liquor in the metathesis chamber of the EDM process. The EDM had shown the most excellent chloride ion removal ability. We found that A3 was the best membrane for the EDM process of tobacco liquor.
采用一组三种离子交换膜（ACS、TW-A和A3）和模拟烟草提取液，对电渗析复分解（EDM）脱盐进行了研究，以实现选择性离子去除。我们使用完整的实验设计研究了影响EDM脱盐效率的各种因素。首先，进行扩散渗析（DD）以确定不同膜材料在烟草液中不同阴离子的渗透速率。我们得出结论，A3的阴离子渗透速率最快。然而，ACS对不同盐的渗透速率最低。通过检测EDM过程复分解室中目标烟草液的电流、电导率和离子浓度，对EDM过程的研究表明A3具有优异的离子渗透能力。EDM表现出最优异的氯离子去除能力。我们发现A3是烟草液EDM过程的最佳膜。
