| Abstract: | Phthalate esters in plastic tablecloth were determined by means of accelerated solvent extraction and gas chromatography-mass spectrometry(ASE-GC/MS) and ultrasonic solvent extraction and gas chromatography-mass spectrometry(USE-GC/MS).Results show that the ASE-GC/MS method is superior to USE-GC/MS in terms of measurement precision,and the value measured by the latter is about 80% of that measured by the former.Besides,a recovery of 89.0%-95.5% and RSD of 4.3%-10.4% were obtained with ASE-GC/MS method,while... |
