| Research Abstract |
Thermo-responsive polymers containing amino functionalities were prepared by the water soluble carbodiimide-mediated condensation of chitosan or polyallylamine with poly (N-isopropylamine). The polymers became water-insoluble above the lower critical solution temperature (ca. 33℃) and quantitatively collected as the coagulates. Tyrosinase and peroxidase/hydrogen peroxide were useful for the oxidation of phenols that can bind to the amino moiety of polymer. Under the optimum conditions, 300mg/l of phenol was completely eliminated from water within 10min. Varieties of phenolic compounds and estrogenic hormones were almost completely removed. The applicability of the proposed method to the wastewater treatment was successfully demonstrated.
