Adsorption of Reactive Blue 19 as an Anionic Dye by PVA/CS/Triton X-100 Electrospun Nanofibers

Reactive dyes, due to their high molecular weight and aromatic structure, are considered more challenging pollutants than other dyes. They are highly soluble in water and are not easily removed through conventional treatment methods. The use of adsorbents to eliminate these dyes is a common approach. In this study, polyvinyl alcohol/chitosan (PVA/CS) nanofibers modified with Polyethyleneimine (PEI) were utilized as adsorbents for the removal of reactive dyes. Both polymers possess high hydrophilicity and biodegradability. The electrospinning technique, a common and cost-effective method, was employed for nanofiber fabrication. Additionally, Triton X-100 was used to facilitate the electrospinning process and enhance the quality of nanofibers.
