| Research Abstract |
Using bacteria Pseudomonas, which is known to decompose pnonylphenol (one of endocrine disruptors), and pore-controlled activated carbon, a new water treatment without secondary waste method has been researched. Though such biochemical reaction rates are slow generally, application of adsorption-catalysis can improve this demerit.
(1) It has been found that pnonylpenol in water is most easy to adsorb 4~5nm sized pores in activated carbons. It became to be possible to increase 4~5nm pores in more mild baking condition than usual one, mixed water vapor.
(2) palkylphenol with longer allcylchain tended to adsorb more quickly than with shorter one.
(3) Adsorption-catalisis made palkylphenol decompose ca. 60% quickly (30℃,100rpm), after more than 16 days, its benzene ring began to decompose.
(4) An electric cell was made for control adsorption/desorption of bacteria on activated carbon.. New impedance measurement and analysis method was designed to investigate adsorption mode of organic molecules.
