Belloni, C. (author), Korving, L. (author), Witkamp, G.J. (author), Brück, E.H. (author), Dugulan, A.I. (author)Phosphorus (P) removal from freshwater bodies to ultra-low concentrations is fundamental to prevent eutrophication, while its recovery is necessary to close the P usage cycle. Iron oxide-based adsorbents seem promising candidates, being abundant, cheap, and easy to synthesize compounds, with good affinity for P. Affinity is the key parameter...journal article 2023

Belloni, C. (author), Korving, L. (author), Witkamp, G. J. (author), Brück, E.H. (author), de Jager, P. (author), Dugulan, A.I. (author)Hybrid anion exchange adsorbents (HAIX) seem promising to prevent eutrophication and recover phosphate (P). HAIX consist of an anion exchange resin (AIX) backbone, promoting anion physisorption (outer-sphere complex), impregnated with iron (hydr)oxide nanoparticles (NPs), for selective P chemisorption (inner-sphere complex). In this work, for...journal article 2023

Belloni, C. (author), Korving, L. (author), Witkamp, G.J. (author), Brück, E.H. (author), Dugulan, A.I. (author)Iron oxide-based adsorbents showed potential to reach ultra-low phosphorus (P) concentrations to prevent eutrophication and recover P. High affinity, high capacity at low P concentrations (<1 mg L<sup>−1</sup>), good stability, and reusability of the adsorbent are key factors for economic viability. In this study, nanoparticles of goethite...journal article 2024
