Sažetak

Water pollution, particularly from heavy metal ions, remains a major environmental challenge, necessitating the development of cost-effective and sustainable adsorbents. This study presents a novel polyvinyl alcohol (PVA)/chitin composite foam synthesized via solid-state shearing milling (S3M) and supercritical carbon dioxide (scCO2) foaming technologies. The composite foams with high cell density exhibited improved structural integrity, mechanical strength, and adsorption capacity. The composite foam with 10% chitin loading demonstrated a 193% increase in copper ion adsorption and a 56% improvement for lead ions compared to pure PVA foam. The results indicate that the synergistic effect of PVA and chitin enhances the comprehensive performance of the foams parts.
