摘要: A gas chromatography–mass spectrometry (GC-MS) method was developed for the identification and quantification of 2,8-dichlorodibenzo-p-dioxin (2,8-DCDD) in toothpaste mouthwash consumer products. Liquid–liquid extraction solid-phase were used sample preparation. The limit detection 0.96 ng/g 0.83 ng/g mouthwash. accuracy represented by relative errors less than 12.5 %. intra-day inter-day precision, which are standard deviation values, within 11.2 10.6 %, respectively. successfully applied to analyze 2,8-DCDD products, as well that from photo-degradation triclosan spiked both matrix.
