摘　　要：实验通过电渗析的方法以3362W膜和AM-203阴离子交换膜浓缩β-萘磺酸溶液。实验考察了浓度,温度,电流和时间对电渗析过程的影响。实验结果表明,采用电渗析技术在25℃条件下可有效的实现β-萘磺酸稀溶液的浓集,且AM-203膜的性能优于3362W膜。Anion-exchange membranes 3362W and AM-203 were evaluated for facilitating the concentration of β-Naphthalenesulfonic acid by electrodialysis. The effect of concentration, temperature, ccurrent, and time on the electrodialysis process were studied. Experimental results indicated that electrodialysis was an effective method for concentrating β-Naphthalenesulfonic acid at 25℃. The performance of the AM-203 membrane was better than 3362W membrane.
