气相色谱质谱法测定再生塑料中5种新型阻燃剂
Determination of novel flame retardants in recycled plastic by gas chromatography-mass spectrometry
摘要
Abstract
In this study,a reliable gas chromatography-mass spectrometry method was developed for simultaneous deter-mination of five novel flame retardants,including 4-tert-butylphenyl diphenyl phosphate(MDPP),2-ethylhexyltetrabro-mobenzoate(TBB),bis(4-tert-butylphenyl)phenyl phosphate(DBPP),tris(p-t-butylphenyl)phosphate(TBPP),and bis(2-ethylhexyl)-2,3,4,5-tetrabromophthalate(TBPH),in recycled plastics.The method employed ultrasonic-assist-ed methanol extraction,followed by separation on a DB-5HT capillary column(15 m×0.25 mm×0.10 μm)with tem-perature programming.Identification and quantification were performed using both full scan and selected ion monitoring modes with external standard calibration.The method demonstrated excellent linearity(R²>0.998)across a concentra-tion range of 0.05～10 mg/L.Method validation showed detection limits of 0.12～0.18 mg/kg and quantification limits of 0.40～0.60 mg/kg.Average recoveries at three spiking levels(0.5,20 and 100 mg/kg)ranged from 95.7%to 106.4%,with relative standard deviations(RSDs,n=7)between 0.2%and 5.1%,confirming the method's accura-cy and precision for analyzing these emerging contaminants in plastic matrices.关键词
