One-Step Fabrication of Dual Responsive Lignin Coated Fe3O4 Nanoparticles for Efficient Removal of Cationic and Anionic Dyes
A new, simple one-step approach has been developed to synthesize lignin and lignin amine
coated Fe3O4 nanoparticles. These nanoparticles (lignin magnetic nanoparticles (LMNPs)
and lignin amine magnetic nanoparticles (LAMNPs)) are found to possess not only magnetic
response but also pH-dependent adsorption behavior. Results show that the combination of
lignin with nanoparticles increased the adsorption capacities 2–5 times higher than other
traditional single lignin based adsorbents (211.42 mg/g for methylene blue (MB) by LMNPs …
