The morphological properties and adsorption potential of lignin-based porous
microspheres (LgMS) for heavy metals ions were investigated. LgMS were produced via
suspension copolymerization of unmodified or acryloyl modified kraft lignin with amine
(polyethylene imine - PEI) or acrylate (trimethylolpropanetriacrylate - TMPTA) functional
polymers. Structural and morphological characterization of LgMS was performed using
FTIR, BET, and SEM techniques. Copolymerization of the unmodified lignin and PEI, using
epoxy chloropropane cross-linker, provided highly porous LgMS, with 800 ± 80 μm
diameter, 7.68 m2g−1 surface area and 7.7 mmol g−1 of terminal amino groups. The LgMS
produced by copolymerization of the acryloyl functionalized lignin and TMPTA provided a
decrease in LgMS diameter (253 ± 42 μm), while surface area and porosity increase, 69.4 m2
g-1and 59%, respectively. The effect of acryloyl functionalization of kraft lignin on the
LgMS adsorption capacity for Ni2+ ions was a...lso studied in a comparative study. The results
showed that final adsorption performances of LgMS were affected by the key factors
including lignin functionality and the LgMS synthesis condition. Lower adsorption capacity
of 22.6 mg g-1 for Ni2+ was observed for acryloyl LgMS due to lower affinity for formation
electrostatic interactions of Ni2+ ions with phenol/hydroxyl groups responsible for
adsorption. Opposite was found for amino LgMS where 49.4 mg g-1was achieved. However,
this study indicated that removal of heavy metal ions from wastewater can be realized
through the application of eco-friendly lignin-based porous microspheres.
