| Abstract: | Objective:To establish a simple method for determination of 7 phthalate esters (PEs) by gas chromatography/mass spectrometry (GC/MS). Methods:Vacuum cleaner was used for gathering the house dust,and n-hexane was added and extraction was performed in an ultrasonic bath. The supernatant was concentrated and then added with n-hexane to 0.2 ml. PEs were determined by GC/MS. Results:Seven PEs had highly efficient separation within 22 minutes and showed good linearity within 5~2 000 ng/ml range with correlation coefficients all beyond 0.998. The relative standard deviations were 5.66%~18.03%,and the recoveries were 87.73%~110.63%. Conclusion:This method was a economic,fast,simple,sensitive and reproducible enough for settled-dust PEs measurements in house dust with large sample size. |
