Polymeric membranes functionalized with deep eutectic solvents as separators in microbial fuel cells

Popis výsledku v původním jazyce

This study explores novel membranes based on deep eutectic solvents (DES) combined with commercial polyvinyl chloride (PVC) for bioenergy generation in microbial fuel cells (MFCs) utilizing wastewater. The incorporation of DES into these systems provides a cost-effective and environmentally sustainable approach for fabricating exchange membranes, thanks to their unique properties, including ionic conductivity, solvation capabilities, ease of fabrication, and biodegradability. Polymer membranes were synthesized using a solution casting technique, incorporating a DES composed of Aliquat-336 (trioctylmethylammonium chloride) and menthol in a 1:1 M ratio. The final membrane compositions included the eutectic phase at percentages of 30 %, 50 %, and 70 %, which were compared to pristine PVC membranes. Characterization techniques such as scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), ionic exchange capacity (IEC), ion transport number, water uptake and swelling ratio were employed to assess membrane properties. This study focuses on MFCs used for wastewater treatment and energy recovery, highlighting the potential of DES-based membranes as a more sustainable alternative to traditional materials and establishing a new avenue for the use of DES in bioelectrochemical applications. Specifically, the membranes containing 50 % DES exhibited promising performance, demonstrating the potential of DES as an active phase in membrane technology, with a power density of 292.2 mW m-3 and a COD removal rate of 78.3 %.
