Development of an innovative method to modify magnetic lignin by a green modifier agent for water treatment

In the present work, a novel and eco-friendly method was developed to prepare a green multifunctional adsorbent by modifying magnetic lignin via a beta-cyclodextrin agent (β-CD@lignin/Fe۳O۴). The produced β-CD@lignin/Fe۳O۴ were then characterized using Fourier transform infrared spectroscopy (FTIR). The β-CD@lignin/Fe۳O۴ was employed as an adsorbent to remove methylene blue from aqueous solutions. The results showed that methylene blue removal could reach up to approximately ۹۷% under an initial concentration of ۲۰ mg L-۱, pH ۷, contact time of ۴۵ min, and adsorbent dosage of ۰.۶ g L-۱.
