In this work, an acrylic-polypropylene grafting copolymer (PP-g-AA) was prepared by 60Co γ-rays irradiation grafting with acrylic acid (AA) onto polypropylene (PP) fiber. The esterification PP-g-AA fiber (PP-g-COOR) was prepared by the esterification of PP-g-AA with C8 alcohol via SOCl2 as the intermediate. The PP-g-COOR fiber was utilized to adsorb and enrich trace dibutyl phthalate (DBP) in water. The results indicated that PP-g-COOR fiber exhibited a good adsorption property of DBP. The adsorption property of PP-g-COOR fiber was greatly enlarged 25 times than the PP-g-AA. The distribution coefficient of DBP on PP-g-COOR fiber depended on the pH values of aqueous phase and the initial concentration of DBP. In general, the PP-g-COOR fiber was better for the adsorption and enrichment of DBP.
