  A composite membrane and method for making the same, comprising a porous support and a polyamide surface. The subject membrane provides improved flux and/or rejection rates. The subject membrane is further capable of operating at lower operating pressures. The subject method includes reacting a polyfunctional amine with a polyfunctional acyl halide to form a polyamide. The method includes the step of contacting a complexing agent with the polyfunctional acyl halide prior substantial reaction between the polyfunctional acyl halide and a polyfunctional amine. The subject process is easily adapted to commercial scale manufacturing processes and is particularly suited for making nanofiltration and reverse osmosis composite membranes.

  一种复合膜及其制造方法，包括多孔支架和聚酰胺表面。该膜提高了通量和/或排斥率。该膜还能在较低的工作压力下工作。该方法包括将多官能团胺与多官能团酰基卤反应生成聚酰胺。该方法包括在多官能酰基卤与多官能胺发生实质性反应之前，将络合剂与多官能酰基卤接触。该主题工艺很容易适用于商业规模的制造工艺，尤其适用于制造纳滤和反渗透复合膜。
