| Outline of Final Research Achievements |
We succeeded in the development of cyclic oligosaccharide-derived polymers by which harmful polychlorobiphenyls (PCBs) contaminated in insulating oil can be completely removed and recovered from the oil. These polymers can be recycled many times for PCB adsorption without any loss in the adsorption ability. Furthermore, we developed cyclic oligosaccharide derivatives which enabled the effective removal and recovery of harmful trans-fatty acids from edible oils. Those adsorbents can be recycled for trans-fatty acids adsorption. By passing the contaminated oils through a column loaded with the cyclic oligosaccharide adsorbents, we can remove and recover the harmful compounds from the oils safely and efficiently.
