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).

This review provides overview current research advances pervaporation EG-containing mixtures (water/EG methanol/EG), as well detailed analysis relationship performance with membrane structure properties materials. It discussed that controlled change transport possible modification methods such treatment solvents, introduction nonvolatile additives, polymer blending, crosslinking, heat treatment. The use various modifiers also described, particularly positive effect on selectivity highlighted. Among polymers, hydrophilic PVA-based membranes stand out optimal they offer dehydrating. Fabricating TFC microporous support layer appears be viable approach development productivity without loss. Special attention given recovery methanol from EG, extensive studies membranes. Membranes based CS/PVP blend inorganic are specifically promising removal. With regard wettability properties, it worth mentioning hydrophobic polymers (e.g., SPEEK, PBI/PEI, PEC, PPO) capable exhibiting much higher due diffusion limitations.

Abstract Polymer fiber surface modification by low temperature plasma has received much attention in recent years. The kinetic behavior and reactive species distribution can be totally different with the existence of fiber. In this work, a 2D axisymmetric fluid model is established to study interaction between an atmospheric pressure jet single relative permittivity ( ε r = 1.5 80, respectively). Division ionization wave observed when approaching fiber, followed full wrapping surface. Afterward, travels across continues propagate forward. Significant effects induced variation fiber’s are observed. For high electric field (EF) region shifts from south pole (SP; closer tube) north (NP; opposite side SP), but EF remains at SP for 80. This due large potential difference on 1.5. Furthermore, time-averaged fluxes main ions (He + , N 2 O ) excited (Hes, N, O) analyzed. It found that 80 NP significantly higher than Therefore, increasing dielectric constant would increase NP.

Abstract Cellulose acetate (CA) membranes used in reverse osmosis (RO) desalination techniques often face fouling challenges.
