含有NaCl的稀谷胱甘肽溶液需要提纯浓缩。纳滤（NF）是一种很好的解决方案，它可以完全过滤谷胱甘肽，同时完全渗透NaCl。市售的NF膜不能同时满足这两个目标。因此，在本研究中，我们通过在薄膜上交替聚电解质的层层组装（LBL）来修饰市售的NF膜，以增加谷胱甘肽的排斥和膜对NaCl的选择性。聚苯乙烯磺酸盐（PSS）为阴离子型聚电解质，聚二烯基二甲基氯化铵（PDADMAC）为阳离子型聚电解质。在含2 g/L NaCl的1 g/L合成谷胱甘肽溶液中，在800 kPa的压力下，研究了改性膜的分离性能。结果表明，谷胱甘肽的排异率由未修饰的74%提高到97.27% ([PSS/PDADMAC]10/PSS)，选择效果显著。
Dilute glutathione solutions containing NaCl need to be purified and concentrated. Nanofiltration (NF) would be a good solution, provided that it could completely reject glutathione while permeating NaCl entirely. Commercially available NF membranes are incapable of meeting both of these targets. Therefore, in this study, we modified a commercially available NF membrane by the layer-by-layer (LBL) assembly of alternating polyelectrolyte on thin films, to increase both the glutathione rejection and the membrane selectivity for NaCl over glutathione. Poly(styrene sulfonate) (PSS) was selected as the anionic polyelectrolyte, and poly(diallyldimethylammonium chloride) (PDADMAC) was chosen as the cationic polyelectrolyte. The separation performances of the modified membranes were studied with 1 g/L synthetic glutathione solutions containing 2 g/L NaCl at a pressure of 800 kPa. The results demonstrated that the glutathione rejection increased from 74% (unmodified) to 97.27% ([PSS/PDADMAC]10/PSS) and the selecti...
