Determination of phthalate esters in the children's products using ultrasonic extraction and gas chromatography

摘要

A method for the detection of PAEs (16 kinds ) in the children's products using ultrasonic extraction and gas chromatography were investigated in this study. The method was linear between 0.500 and 10.000 μg ml~(-1), R~2 between 0.995 and 0.999, LOQ between 0.704 and 1.585 μg ml~(-1). The method repeatability was between 1.2% and 13% RSD. The experiment results showed that the children's products samples containing different kinds of PAEs. DIBP and DCHP were frequency found in all sample. The PAEs concentration of the children's products sample was between 0.019 and 6.301 μg ml~(-1).
