Liquid chromatography coupled to high resolution mass spectrometry( L7--IHBD) was 2+6 to establish & high throughput and sensitive method for 18 phthalic acid esters (PAEs) in textiles. The method 8as applied to screen PAEs in 413 textile samples and 7 434 pieces of test data were analyzed. Further discussion 8as conducted about specific compounds, textile materials, detected value distribution and positive rate of samples. Twenty-nine percent of samples were detected with PAEs, and no samples were detected beyond regulations. Diisobutyl phthalate ( DiBP), Dibutyl phthalate ( DBP) and Di-2-ethylhexyl phthalate ( DEaP ) were detected with high frequency, and most samples were fabrics with coating and printing. This stud- can be used to reflect distribution of phthalate residues in textiles on the market and provide data support for risk assessment of PAEs for textile producers and consumers.

A rapid method for the determination of five organophosphorus flame retardants (OPFRs) in textile wastewater was established by dispersive liquid-liquid microextraction (DLLME) based on solidification of floating organic drop (SFO) coupled with ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). The analytes were extracted from the water samples by SFO-DLLME, which was performed using a mixture of an extraction solvent that was less dense than water, 1-undecanol, and a dispersive solvent, methanol. The influences of the SFO-DLLME parameters on the extraction efficiencies were studied. 1-Undecanol (extraction solvent, 400 μL) and methanol (dispersive solvent, 300 μL) were added to textile wastewater (containing 2 g NaCl) with pH between 6 and 9, and the solution was shaken for 2 min. Under optimum conditions, the linear ranges of the proposed method were from 2 μg/L to 100 μg/L with correlation coefficients ( R 2 ) above 0.99 for all the analytes. The limits of detection ( S/N =3) ranged from 2 μg/L to 5 μg/L. The precision of the method was evaluated in terms of repeatability; the relative standard deviations varied from 2.7% to 11.2% ( n =6). The relative recoveries ranged from 71.6% to 117.6% for all analytes. Only 3 of the 11 selected samples were tested positive for OPFRs, and the total concentrations of OPFRs in them were in the range of 2.6-3.4 μg/L. Hence, this method is accurate, environmentally friendly, fast, and convenient for the routine analysis of OPFRs in textile wastewater.
