| Abstract: | A method for simultaneous determination of 22 phthalate esters(PAEs) plasticizers in plastics toys by gas chromatography-mass spectrometry(GC-MS) with subsection SIM mode was developed.The results show that the correlation coefficients are over 0.999,the detection limits are 1.28~128.91 mg/kg,the average recovery rates are 70.83%~107.95%,and the relative standard deviations are 3.61%~9.79%.The method is simple,sensitive and repeatable,which can meet the test requestment of PAEs in plastics toys. |
