Abstract
Phoenix dactylifera leaf extract was immobilized within cross-linked polyvinyl alcohol (PVA) for the removal of methylene blue (MB) from aqueous solutions. The Ultraviolet–visible (UV–vis) and Fourier transform infrared spectroscopic techniques were utilized to shed light on the functional groups accountable for the adsorption process. The adsorption experiments were conducted as a function of different operating variables (contact time, adsorbent dosage, initial dye concentration, and pH value). The developed P. dactylifera/PVA matrix can be considered as a low-priced green adsorbent with high efficiency for the removal of MB from aqueous solution.
