摘要: 为了将具有高表面吸附能和高孔隙率的静电纺纳米纤维膜作为一种新型膜材料应用于染料废水处理,达到高效过滤染料的目的,研究了在0.1MPa恒压死端过滤条件下静电纺PA6/66纤维膜对0.1g?L-1分散蓝2BLN悬浮液和弱酸性蓝N-RL水溶液的过滤效果,通过SEM、孔径分析测试仪、纳米粒径测试仪和紫外可见光分光光度仪测试并分析了静电纺PA6/66纤维膜的表面形态、孔隙结构、染料粒径分布及对染料的截留性能。结果表明,连续过滤1h后,静电纺PA6/66纤维膜的表面均沉积一层致密的滤饼,对分散蓝2BLN的截留率达95.6%,对弱酸性蓝N-RL的截留率仅为35.1%,但是对两类染料的过滤通量却相似。

Abstract: In order to separating dyes from dye waste water efficiently, electrospun nanofibrous membrane, which has higher surface adsorption energy and higher porosity than traditional membrane, was used as a novel membrane material to treat dye waste water. This paper has studied the filtration property of PA6/66 electrospun fibrous membrane for 0.1g?L-1 disperse blue 2BLN suspension and weak acid blue N-RL solution with dead-end filtration method under constant pressure o.1MPa. The surface morphology of PA6/66 electrospun fibrous membrane, porous structure, dye particle size and selection property also had been studied by SEM, pore size testing meter, nano-particle size testing meter and ultraviolet-visible spectrophotometer. The results shown that there was a compact cake layer on the surface of the membrane after filtered constantly for 1h, the selection to disperse blue 2BLN was 95.6% and to weak acid blue N-RL was only 35.1%, but the filtration fluxes to these two dyes were similar.
