摘要:
为了改善氧化石墨烯基纳滤膜在应用时结构稳定性差和应用范围窄的问题,利用乙烯基三乙氧基硅烷(VTES)对氧化石墨烯(GO)进行改性,并接枝聚丙烯酸(PAA),获得具有交联结构和pH值响应性的GO-PAA纳滤膜;对GO粉末、GO-VTES粉末、GO-PAA粉末和纳滤膜进行表征,采用染料刚果红、达旦黄、金橙、结晶紫、罗丹明B和碱性红分析纳滤膜的分离性能。结果表明:在酸性环境下,PAA链静电斥力减弱,链收缩,膜分离效果差;在中性或碱性环境下,PAA链静电斥力大,链伸展,膜分离效果好,纳滤膜对阴离子型染料的分离效果均达99%以上,对阳离子型染料均具有99%以上的吸附分离效果。该GO-PAA纳滤膜具有优异的分离效果和结构稳定性,在染料废水处理领域有着广泛的应用前景。
