Development of Novel Membranes Based on Polyvinyl Alcohol Modified by Pluronic F127 for Pervaporation Dehydration of Isopropanol

Membrane methods are environmentally friendly and can significantly improve the design development of new energy consumption processes that very important nowadays. However, their effective use requires advanced membrane materials. This study aims to performance pervaporation polyvinyl alcohol (PVA)-based for isopropanol dehydration. To achieve this goal, two were applied: (1) bulk modification PVA by Pluronic F127 (2) supported PVA-based using polyphenylene isophthalamide (PA) as a substrate with various porosity. Developed membranes characterized Fourier-transform infrared spectroscopy, scanning electron microscopy (SEM), contact angle measurement, swelling experiments. The concentration influence PA casting solution (12–20 wt.%) on porous (substrates) was investigated in ultrafiltration pure water bovine serum albumin (BSA) well microscopic (SEM atomic force microscopy). developed dense tested dehydration isopropanol. Optimal transport characteristics obtained selective layer containing 3 wt.% onto an (17 substrate: improved permeation flux 0.100–1.164 kg/(m2 h) 98.8–84.6 content permeate (12–80 water).
