The intent of this study was to explore the potential application of polymerin, the mineral-organic fraction from olive mill wastewaters, associated with aluminum oxide (Al2O3) nanoparticles in technologies aimed at remediating water point-source pollution. In comparison with microparticles, the interaction of polymerin with Al2O3 nanoparticles was investigated. Phenanthrene sorption on wet and dry polymerin-particle complexes was also examined. Nanoparticles sorbed polymerin seventy times more than microparticles. Using a complex, microparticles did not show any difference in phenanthrene sorption either if the complex was wet or dry. In contrast, a considerable enhancement of phenanthrene sorption was shown when using a dry polymerin-nanoparticle complex. These findings support the application of polymerin associated with Al2O3 nanoparticles in remediation of water contaminated with HOCs.
