Poly(vinyl Alcohol) and Halloysite -Based Composite Films Crosslinked with Glutaraldehyde for Methyl Orange Removal from Wastewater

Films of Poly(vinyl alcohol) (PVA) and modified halloysite nanotubes (HNT) were fabricated using the solution casting technique to improve the adsorption of methyl orange (MO) dye. Biodegradable glutaraldehyde was employed as a crosslinking agent to ensure strong interactions between the polymer and clay. The resulting PVA/modified HNT films were analyzed using FTIR method. The adsorption test results indicated that the film reinforced with polydopamine-modified halloysite nanotubes adsorbed more methyl orange dye compared to the film reinforced with unmodified halloysite nanotubes, under the same conditions.
