COMPOSITE POLYAMIDE MEMBRANE INCLUDING TRI-HYDROCARBYL PHOSPHATE |
| 摘要 |
A method for making a composite polyamide membrane comprising a porous support and a thin film polyamide layer, wherein the method includes:
i) applying a polar solution comprising a polyfunctional amine monomer and a non-polar solution comprising a polyfunctional acyl halide monomer to a surface of a porous support and interfacially polymerizing the monomers to form a thin film polyamide layer, and
wherein the non-polar solution further comprises a tri-hydrocarbyl phosphate compound represented by Formula (I):
;wherein R1, R2 and R3 are independently selected from hydrogen and hydrocarbyl groups comprising from 1 to 10 carbon atoms, with the proviso that no more than one of R1, R2 and R3 are hydrogen; andii) applying an aqueous solution of nitrous acid to the thin film polyamide layer. |
