摘要：
Several ionomer membranes, GFT and over-crosslinked GFT hydrophilic membranes were studied in pervaporation of water-organic base [pyridine, dimethylisopropylamine (DMIPA), dimethyl propane diamine (DMPDA) and tetramethyl propane diamine (TMPDA) ] mixtures. Over-crosslinked GFT membranes showed the best selectivity in all cases with rather low fluxes. RAI 1010 (polystyrenesulfonic grafted onto Teflon) membranes generally exhibited the best overall performances. The selectivity of a given membrane for the studied amine decreases in the following order DMIPA > pyridine > DMPDA.
