AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modifiedplant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained fromwaste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the producedsilica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigatethe mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization ofcomposite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) andmeasurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles withvinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and loadfor comparison of measurements between different composite materials and to enable the choice of the material in terms ofoptimization of the quality of reinforcement and quality of interphase determined by surface modification.

AB  - 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 also 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.
