The removal of an endocrine disrupting compound, bisphenol A (BPA), from model solutions by selected nanofiltration (NF) and reverse osmosis (RO) membranes was studied. The commercially available membranes NF 90, NF 270, XLE BWRO, BW 30 (Dow FilmTech), CE BWRO and AD SWRO (GE Osmonics) were used to compare their performances for BPA removal. The water permeability coefficients, rejection of BPA and permeate flux values were calculated for all membranes used. No significant changes in their BPA removal were observed for all tight polyamide based NF and RO membranes tested except for loose NF 270 membrane. The polyamide based membranes exhibited much better performance than cellulose acetate membrane for BPA removal. Almost a complete rejection (≥ 98%) for BPA was obtained with three polyamide based RO membranes (BW 30, XLE BWRO and AD SWRO). But cellulose acetate based CE BWRO membrane offered a low and variable (10-40%) rejection for BPA.
采用纳滤（NF）和反渗透（RO）膜从模型溶液中去除内分泌干扰物双酚 A（BPA）的研究。使用市售的纳滤膜 NF 90、NF 270、XLE BWRO、BW 30（陶氏 FilmTech）、CE BWRO 和 AD SWRO（GE Osmonics），比较它们对 BPA 去除的性能。计算了所有使用的膜的水渗透率系数、BPA 的截留率和渗透通量值。除了疏松的 NF 270 膜外，所有测试的紧密聚酰胺基 NF 和 RO 膜的 BPA 去除率均无明显变化。聚酰胺基膜在去除 BPA 方面的性能明显优于醋酸纤维素膜。三种聚酰胺基 RO 膜（BW 30、XLE BWRO 和 AD SWRO）几乎对 BPA 完全截留（≥98%）。但是，基于醋酸纤维素的 CE BWRO 膜对 BPA 的截留率较低且可变（10-40%）。
