| Abstract: | A SPME-HPLC method is proposed for the determination of DMP, DEP, DBP and DOP using a fiber with phenyl functionalized MCM-41 coating. Extraction/desorption time, extraction temperature and stirring rate for SPME have been optimized. The linear ranges are 1.19×10-4～119 μg/L, 1.12×10-4～112 μg/L, 1.05×10-4～105 μg/L and 9.8×10-5～98 μg/L for DMP, DEP, DBP and DOP, respectively. Corresponding limits of detection are 0.030, 0.027, 0.029 and 0.022 ng/L. This SPME-HPLC technique was employed for practical determination of phthalates in different water samples. The sampling procedures are simple, rapid and solvent-free. High sensitivity and good precision were obtained. |
