具有高酸含量和低偶氮含量的复合聚酰胺膜
摘要：
一种薄膜复合聚酰胺膜，其包含多孔载体和薄膜聚酰胺层，所述膜的特征为具有：i)如热解气相色谱法所测量，0.30％到0.80％偶氮(?N＝N?)含量；以及ii)如RBS在pH 9.5下所测量，至少0.18mol/kg的解离羧酸根含量。
摘要（英）：

A thin film composite polyamide membrane comprising a porous support and a thin film polyamide layer characterized by possessing: i) an azo (-N=N-) content of from 0.30% to 0.80%, as measured by pyrolysis gas chromatography; and ii) a dissociated carboxylate content of at least 0.18 mol/kg as measured by RBS at pH 9.5.
