| 摘 要： | 本文通过对PVDF膜进行接枝、磺化和离子交换负载铁,制备了PVDF催化膜,对其制备条件进行优化,对水通量、截留率、亲水性等性能进行了表征.实验结果表明PVDF膜的接枝率随着KOH浓度和碱处理时间的增加,PVDF膜的接枝率先增加后减小;而随着反应温度以及四丁基溴化铵(TB-AB)增加,PVDF膜的接枝率增大;膜的磺化度随...

| Abstract: | PVDF catalytic membrane was prepared by grafting,sulfonating and ion-exchanging of PVDF membrane.The optimal conditions of the preparation were discussed and the characteristics of PVDF catalytic membrane was characterized by water flux,rejection rate and hydrophilicity.The results showed that the grafting rate of membrane increased and then decreased with the increase of concentration of KOH and the time of KOH,but it increased with the increase of reaction temperature and the content of TBAB added;the sul... |
