Novel highly effective amino-functionalized lignin-based biosorbent in the microsphere geometry (A-LMS) for removal of heavy metal ions, was synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene imine) grafting-agent and epoxy chloropropane cross-linker. Optimization of A-LMS synthesis, performed with respect to the quantity of sodium alginate emulsifier (1, 5 and 10 wt%), provides highly porous microspheres A-LMS_5, using 5 wt% emulsifier, with 800 ± 80 μm diameter, 7.68 m(2) g(-1) surface area and 7.7 mmol g(-1) of terminal amino groups. Structural and surface characteristics were obtained from Brunauer-Emmett-Teller method, Fourier Transform-Infrared spectroscopy, scanning electron microscopy, X-ray photo-electron spectroscopy and porosity determination. In a batch test, the influence of pH, A-LMS_5 dose, temperature, contact time on adsorption efficiency of Ni2+, Cd2+, As(V) and Cr(VI) ions were studied. The adsorption is spontaneous and feasible wi...th maximum adsorption capacity of 74.84, 54.20, 53.12 and 49.42 mg g(-1) for Cd2+, Cr(VI), As(V) and Ni2+ ions, respectively, obtained by using Langmuir model. Modeling of kinetic data indicated fast adsorbate removal rate with pore diffusional transport as rate limiting step (pseudo-second order model and Weber-Morris equations), thus further confirming high performances of produced bio-adsorbent for heavy metal ions removal.
