摘要：
The mass transfer of thiophene through pervaporation(PV) membranes could be facilitated by certain transitional metal ions like Ag+, Mn2+, and Cr3+ thanks to their p complexation with thiophene. In this study, Ag~+, Mn2+, and Cr3+ions were loaded onto the polyether block amide(PEBAX)/PAN composite membranes and were tested on the performance for separation of thiophene/n-heptane mixture. Pervaporation test results showed that the pervaporative separation index increased significantly to 73.1%, 75.5%, and 97.2% at 30 oC for the Ag~+-, Mn2+-, Cr3+-loaded PEBAX membranes, respectively,as compared to the pristine PEBAX/PAN composite membrane.
