【 摘 要 】

A novel water soluble poly (Arlene ether nitrile) (PEN) containing pendent carboxyl and sulfonic acid groups was synthesized, which displayed high reactivity to different metal ions and Rhodamine B (ChB). After a crosslinking with certain metal ions, the PEN produced obvious precipitate in aqueous solution. Moreover, the precipitate was capable to adsorb ChB and the effect of operational parameters (contact time, dye concentration, temperature and pH) on RhB removal was studied. Results showed the adsorption capacity at 25 ° C could reach up to 112.5 mg/g.
