Outline of Final Research Achievements

Methyl isoborneol (MIB) is a musty odor substance, it is very strong malodorous substances with non-toxic. Therefore it is important to remove from the tap water. But now, the adsorbent for adsorbing only the MIB is not developed.　In this study, we performed adsorption experiments with isoborneol an inexpensive MIB similar materials using a polymer membrane containing host molecules that interact with a specific substance.　Then, we examined the new adsorbent development of the MIB on the adsorption capacity and selectivity.
In addition, we examined adsorption selectivity of imprint membrane by using IB and bisphenol A (BPA) or p-nonylphenol (P-Np) as endocrine disrupting chemicals. As a result, host molecules was able to confirm the adsorption selectivity of the membrane to imprint because IB is adsorbed preferentially to the membrane than p-Np.
