| Abstract: | Eight new carbon adsorbents derived from polyimide copolymer of 4,4'-bis (maleimododiphenyl)methane and divinylbenzene (BM-DVB) were prepared using a variety of methods. The influence of carbonization, steam or phosphoric acid activation on chemical structure and texture of the carbons has been studied. Adsorption-desorption properties of the carbons were estimated based on recovery determinations for, phenol, its chlorinated derivatives and naphthalene from aqueous solution. The results showed that the best adsorption-desorption properties have polymer-based carbons obtained by high temperature steam activation.Revised: 13 February 2006 and 3 April 2006 |
