| 摘 要： | 采用等离子体辉光放电技术,在以聚苯乙烯为基膜的阳离子交换膜表面接枝苯磺酸甜菜碱(SBMA)单体,制备出具有高选择透过性的阳离子交换膜。对改性前后的膜进行扫描电镜(SEM)、傅里叶红外光谱分析(FTIR)及氯离子泄漏率测试,表征膜的改性效果。结果表明:在SBMA浓度为60g/L,等离子照射强度为0.7 W/cm2,照射时间为7min,照射气体氛围为氩气的条件下,改性效果最佳。改性膜含有的活性基团明显增多,表面致密均匀,氯离子泄漏率由原膜的14%降低至2%以下。

| Abstract: | The cation exchange membrane with high selectivity was prepared by grafting benzenesulfonic acid betaine (SBMA) on the polystyrene-based cation exchange membrane by plasma glow discharge.In order to characterize the modification of the membrane, the SEM, FTIR and chloride ion leakage rates were measured before and after the modification. The results showed that the modified effect was the best when SBMA concentration was 60 g/L, the intensity of plasma irradiation was 0.7 W/cm2, the irradiation time was 7 min, and the irradiation gas atmosphere was argon. After modification, the active groups contained in the membrane were obviously increased and the surface density was uniform. The ion chloride leakage rate of the modified membrane decreased from 14% to 2%. |
