| Abstract: | The self-made PA/PVDF hollow fiber composite nanofiltration membrane was characterized and its structure and contact angle were discussed in this article.And the effects of different operator conditions and materials on PA/PVDF hollow fiber composite nanofiltration membrane were studied.The experimental results show that the multivalent salt and organics(molecular weight>300) could be effectively rejected by the prepared PA/PVDF hollow fiber composite nanofiltration membrane;corresponded to the scope of nanofiltration membrane's separation. |
