摘要

去除盐分一直是废水处理的难题。利用纳滤膜是一种很有前景的方法。然而,目前可用的纳滤膜在去除单价盐方面效果较差。在这项研究中,为了实现制作电荷镶嵌膜的初步目标,在聚醚砜(PES)或聚丙烯腈(PAN)支撑膜上制作了电荷图案的纳滤膜,对一价和二价盐的去除效果相似。这些膜是通过两步层组装制成的,首先将带负电荷的聚苯乙烯磺酸盐(PSS)颗粒固定在聚乙烯醇(PVA)层中,然后涂上带正电荷的聚乙烯亚胺(PEI)层。PVA 和 PEI 都是用戊二醛交联的,而戊二醛最初是浸渍在支撑膜中的。在制造过程中,支撑膜的类型、纳米粒子、PVA 和 PEI 的浓度以及进料 pH 值和盐浓度对所获得的复合膜的分离性能起着重要作用。使用 0.5 wt.% PVA 和 0.05 wt.% PSS 制造第一层电荷图案 NF 膜,然后涂覆 0.5 wt.与多价盐(Na2SO4、MgSO4 和 MgCl2;∼74%)相比,PEI 溶液对一价盐(NaCl;∼82%)的阻隔率更高,PES 膜的渗透率为 5.5 LMH/bar,PAN 支撑膜的渗透率为 3.1 LMH/bar。

Charge-patterned nanofiltration membranes with polystyrene sulfonate particles and polyethyleneimine in cross-linked polyvinyl alcohol

Removing salinity has always been a challenge for wastewater treatment. Utilizing nanofiltration (NF) membranes is a promising approach. However, currently available NF membranes are less effective in monovalent salt removal. In this study, work toward the initial aim of fabricating charge mosaic membranes led to charge-patterned NF-selective films on polyether sulfone (PES) or polyacrylonitrile (PAN) support membranes, with similar rejection for mono- and divalent salts. The membranes were fabricated by a two-step layer assembly of first negatively charged polystyrene sulfonate (PSS) particles immobilized in a polyvinyl alcohol (PVA) layer, followed by coating a positively charged polyethyleneimine (PEI) layer. Both PVA and PEI were crosslinked using glutaraldehyde that had initially been impregnated into the support membrane. The type of support membrane, nanoparticle, PVA, and PEI concentrations during fabrication, as well as feed pH and salt concentration, play significant roles in separation performance of obtained composite membranes. Charge-patterned NF membranes fabricated using 0.5 wt.% PVA and 0.05 wt.% PSS for assembly of the first layer followed by coating 0.5 wt.% PEI solution had even somewhat higher rejection for monovalent salt (NaCl; ∼82%) compared to multivalent salts (Na2SO4, MgSO4, and MgCl2; ∼74%), at a permeance of 5.5 LMH/bar on the PES and 3.1 LMH/bar on the PAN support membrane.
