Synthesis and characterization of new polymer sorbents based on EGDMA and cellulose

In this article bio-based and cheap microcrystalline cellulose was used as a modificator for the synthesis of polymeric sorbents based on ethylene glycol dimethacrylate (EGDMA) and styrene (St). Cellulose was previously modified with methacrylic anhydride. The polymerization reaction was carried out in an aqueous medium with the addition of polyvinyl alcohol using the suspension polymerization technique. The chemical structure of the obtained sorbents was confirmed by ATR-FTIR analysis. In the next stage of the research, the materials were tested for their sorption capacity to remove organic dyes of acidic and basic type from aqueous solutions.
