Harnessing plastic waste for sustainable membrane filtration with trimodal structure through acid-catalyzed oxidation

Chemical Engineering Journal, Journal Year: 2024, Volume and Issue: 486, P. 150230 - 150230

Published: March 12, 2024

Polyolefin waste is among the most generated yet least recycled. Despite its potential as a feedstock of superhydrophobic membranes for organic solvent filtration, it remains challenge to achieve high selectivity and permeability viscous oils. In this study, we valorized polyolefin into trimodal water filtration through acid-catalyzed oxidation void inducer. This approach enabled creation with exceptional wettability strength, characterized by combination micropores, macrovoids (30–70 µm), cavities (150–200 µm). The introduced oxygen moieties membrane structure, resulting in reduced contact angle, improved hydrophilicity, increased permeability. micropores facilitated capillary action, efficient passage, acted oil reservoirs, optimal oil–water separation. Various were synthesized using low-density high-density polyethylene (PE), polypropylene (PP), their blend. obtained results compared commercial membranes, revealing flow rate 43 ml/min, retention capacity 261 mg, an removal efficiency ranging from 84–94 %. Furthermore, exhibited recyclability, demonstrating stability over at 10 cycles. hybrid process transforms plastic achieving balance between superoleophilicity hydrophilicity.

Published: May 22, 2024

Traditional bulk adsorbents, employed for the removal of dyes and metal ions, often face drawback requiring an additional filtration system to separate filtrate from adsorbent. In this study, we address limitation by embedding adsorbent into polymer matrix through a process involving dissolution–dispersion, spin-casting, heat-stretching. Selective dissolution dispersion facilitate integration matrix. Meanwhile, spin-casting ensures formation uniform thin film structure, whereas heat-induced stretching produces porous with reduced water contact angle. The selectively captures dye molecules, while structure contributes permeability.
