作者任顺（2019）在《含有磺酸基团聚酰胺6膜的制备及应用》一文中研究指出：本文通过带有磺酸基团的单体5-磺基水杨酸（5SA）和2-氨基-5-磺基苯甲酸（5SAA）分别与己内酰胺进行共聚,将磺酸基团引入到PA6分子两端,制备了两种磺化聚酰胺6（SPA6和SPAA6）,并分别研究了其成膜性能。首先根据膜的表观及SEM微观形貌确定了制备SPA6膜的最佳凝固浴条件,通过正交试验确定了SPA6的最佳成膜条件:SPA6固含量为30wt%,晾膜时间为120 s,刮膜厚度为200 μm。SEM表明SPA6膜呈现颗粒堆积微观形貌,EDS能谱S元素面扫结果表明,随SPA6浓度提高,膜中S元素的分布更加致密、均一。通过TEM测试对成膜机理进行了探究,SPA6在溶液中会自组装形成纳米胶束,浸入凝固浴之后,胶束转变为纳米纤维,在相转变过程中固化形成球状颗粒,颗粒堆积形成膜,颗粒之间的缝隙围成充满磺酸基团的膜孔道。膜表面Zeta电位测试表明膜带有负电荷。最优膜30M对100 mg/L刚果红、甲基蓝和甲基橙截留率分别为99.21%、85.68%、63.06%。100 mg/L刚果红过滤测试,1500 min后截留率仍保持95.48%,展现了较好的性能稳定性。刚果红-纯水三次循环抗污染测试后,通量恢复率达91.84%,说明该膜具有良好的抗污染能力。为进一步优化膜孔,筛选考察了系列带电荷表面活性剂对SPAA6铸膜液影响。SEM和BET测试表明,表面活性剂对膜结构以及平均孔径影响很大。酸性铬蓝K过滤实验发现,自制表面活性剂S20对膜性能的调控最好。添加S20后,可降低膜的粗糙度,提高膜表面负电荷含量。最优膜M2对氯化钠、硫酸钠、氯化镁和硫酸镁的稳定截留率均低于5%,对阴离子染料刚果红、甲基蓝和甲基橙截留率达99.80%、90.81%、85.65%。对酸性铬蓝K（或刚果红）与氯化钠混合溶液的200 h过滤实验显示,两种染料截留率分别为80.18%和98.22%,而氯化钠截留率低于4%,水通量分别为3.68 L·m-2·h-1和3.54 L·m-2·h-1。M2表现出疏松纳滤膜的过滤行为,具有处理染料废水的潜力。
