Batch experimental studies on Acid Blue 25 dye removal by synthesized chitosan containing sodium alginate and halloysite nanotubes.

ABSTRACT: An eco-friendly composite material was developed as a cost-effective and efficient adsorbent for removing Acid Blue 25 (AB25) dye from aqueous solutions. Despite extensive research on dye adsorbents, there remains a need for sustainable and high-performance materials. While chitosan and sodium alginate have shown promise individually, their composite with halloysite nanotubes (HNTs) is less explored. In this study, chitosan/sodium alginate (CSA) and chitosan/sodium alginate/halloysite nanotube (CSAH) composites were synthesized and evaluated for AB25 removal under varying conditions, including pH (3-11), contact time (2-120 min), initial dye concentrations (20-600 mg/L), and HNT content (5-30%). Characterization of the adsorbents was carried out using BET, zeta potential, FESEM, FTIR, EDX,
