| description | <p>The forward osmosis (FO) process has been considered to be a viable option for water desalination in comparison to the traditional processes like reverse
osmosis, regarding energy consumption and economical operation. In this
work, a polyacrylonitrile (PAN) nanofiber support layer was prepared using the electrospinning process as a modern method. Then, an interfacial
polymerization reaction between <span class="inline-formula"><i>m</i></span>-phenylenediamine (MPD) and trimesoyl chloride (TMC) was carried out to generate a polyamide selective thin-film composite (TFC) membrane on the support layer. The TFC membrane was tested
in FO mode (feed solution facing the active layer) using the standard
methodology and compared to a commercially available cellulose triacetate
membrane (CTA). The synthesized membrane showed a high performance in terms
of water flux (16 Lm <span class="inline-formula"><sup>−2</sup></span> h<span class="inline-formula"><sup>−1</sup></span>) but traded the salt rejection (4 gm<span class="inline-formula"><sup>−2</sup></span> h<span class="inline-formula"><sup>−1</sup></span>) compared with the commercial CTA membrane (water flux <span class="inline-formula">=</span> 13 Lm<span class="inline-formula"><sup>−2</sup></span> h<span class="inline-formula"><sup>−1</sup></span> and salt rejection <span class="inline-formula">=</span> 3 gm<span class="inline-formula"><sup>−2</sup></span> h<span class="inline-formula"><sup>−1</sup></span>) at
no applied pressure and room temperature. Scanning electron microscopy
(SEM), contact angle, mechanical properties, porosity, and performance
characterizations were conducted to examine the membrane.</p> |
