| Abstract: | A method was proposed to simuhancously determine the content of 8 kinds of phthalic acid esters in plastic toys by ultra performance liquid chromatography（UPLC）. The 8 kinds of phthalic acid esters were extracted by ultrasonic wave, by using etha- nol as the solvent. The recoveries varied from 93.6% to 98.8% , the relative standard deviations ranged from 0.6% to 2.3%. The detction limits ranged from 0.16 to 0.76 ng. The method can meet the requirement of sumuhanneous determination of 8 kinds phthalic acid esters in plastic toys. |
