文摘In this paper, fibrous chelating exchangers with-N(CH2COOH)2 group have been prepared for the first time by a weakly basic anion exchange fiber (aminated fiber) as the starting materials. The fibers were quite effective for the adsorption of heavy metal ion such as Cu2+. In addition, IR spectrum of the structure of fibers confirms that it is feasible to prepare iminocarboxylic chelating fiber through direct carboxylation reaction.
