| 제목 | Removal of uranium in water system by grafted chitosan with dicarboxylic acid |
| 초록 | The health and environmental protection agencies have recommended safe limit of uranium in drinking water for human beings. The world Health Organization(WHO, 1998) and the United States Environment Protection Agency(USEPA, 1992) in general have recommended 0.002mg/L of uranium concentration in drinkng water as the safe limit. Recentely within a country presented research report have Uranium in groundwater is natural radioactive uranium. Chitin and chitosan had been left unexploited, even though they are widely distributed in natural environment. The authors developed more effective floculants or metal uptaking agents through graft-copolymerization of deliberately selected alkenoic acids onto chitosan. Graft-copolymers are of importance in view of new industrial applications such as water absorbents, ion exchangers, flocculants, membranes, modified electrodes, and principally chelating agents. The author tried to develop a more effective and economical uses of chitosan through chemical modification and develpoment of application methods for purification. |
