COMPOSITE POLYAMIDE MEMBRANE HAVING AZO CONTENT AND HIGH ACID CONTENT |
| 摘要 |
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 0.40% to 1.00%, as measured by pyrolysis gas chromatography; and ii) a dissociated carboxylate content of at least 0.40 mol/kg as measured by RBS at pH 9.5. |
