Outline of Final Research Achievements |
Polychlorobiphenyls (PCBs) have prohibited both their manufacturing and commercial use due to their string toxicity. However the large amounts of oils contaminated with PCBs (several ten mass ppm) are still stored without the appropriate treatment. Under these backgrounds, we focused on novel and highly effective cyclodextrin-based adsorbents. Urethane-crosslinked cyclodextrin polymers were modified to the surface of silica gels via layer-by-layer assembly of cyclodextrin and diisocyanate linkers. The cyclodextrin polymer modified silica gel particles have high adsorption capabilities(with >95% removal efficiency) toward PCBs, such as tetra, penta and hexachlorobiphenyl in oil through the column method.
