New Bio‐Based Furanic Materials Effectively Absorb Metals from Water and Exert Antimicrobial Activity

Abstract

Development of sustainable bio‐based materials for removal of toxic contaminants from water is a high priority goal. Novel bio‐based binary and ternary copolymers with enhanced ion‐exchange, adsorption and antibacterial properties were obtained by using plant biomass‐derived diallyl esters of furandicarboxylic acid (FDCA) as crosslinking agents and easily available vinyl monomers. The synthesized copolymer materials showed higher sorption capacities for NiII, CoII and CuII compared to the commercial ion‐exchange resins, and they maintained their high metal adsorption capacities for over 10 cycles of regeneration. The synthesized copolymer gels containing 1–5 wt % of the crosslinker showed excellent water absorption capacities. The synthesized copolymers with 1 % crosslinker content showed swelling ratios high enough to also act as moisture absorbents. Synthesized copolymers with crosslinker content of 10 wt % performed as contact‐active antibacterials by inhibiting the growth of Gram‐positive (S. aureus) and Gram‐negative bacteria (E. coli, K. pneumonia) in suspension tests.

Recent advances in the development of green furan ring-containing polymeric materials based on renewable plant biomass

“…347 Allylic esters of FDCA and 5,5′-oxybis(methylene)bis[furan-2-carboxylate] were used as crosslinking agents for the modification of polyacrylate, polymethacrylate and polystyrene matrices via free-radical solution copolymerization, resulting in materials with high metal and excellent water adsorption capacities. 348 UV-initiated thiol-ene click crosslinking of diallyl FDCA ester with different polythiols leads to a series of hydrolysable materials with variable softness/stiffness. 349…”

Stabilization of wines with polymers and new bio-based carbon materials

“…It is on the binding of metals that the action of the AAc/DAF and MAAc/DAF copolymers is directed, which also show activity against pathogenic micro flora [12]. After the treatment of wine samples with an initial content of Ni (II) and Cu (II) of 20 mg/dm 3 each, with the copolymers the content of heavy metal ions decreased almost 10 times and was less than 3 mg/dm 3 .…”

“…As sorbents, synthesized polymeric materials from bio-renewable raw materials [12] were used together with activated carbons obtained from wastes of the agricultural industry and the production of 5-HMF [13]. The total exchange capacity for binary copolymers DAF, depending on the amount of the cross linking agent (2.5-10 mol%), was 8.3-9.5 meq/g, and the sorption capacity for heavy metal ions was 365 mg/g and 290 mg/g (dry adsorbent) respectively for Ni (II) and Cu (II).…”

“…The efficiency of removing heavy metal ions was determined by analyzing the difference in the concentration of these metals in wine before and after adsorption. The concentration of heavy metals was determined by the method described in [12].…”
