In situ passive sampling using the diffusivengradients in thin-films (DGT) technique provides time-integrated datanand is developed for measuring OPFRs here. Ultrasonic extraction ofnbinding gels in methanol provided reliable recoveries for all testednOPFRs. Diffusion coefficients of TCEP, TCPP, TDCPP, TPrP, TBP, andnTBEP in the agarose diffusive gel (25 °C) were obtained. Thencapacity of an HLB binding gel for OPFRs was >115 μg perndisc,nand the binding performance did not deteriorate with time up to 131ndays. DGT performance is independent of typical environmental rangesnof pH (3.12–9.71), ionic strength (0.1–500 mmol L–1), and dissolved organic matter (0–20 mg L–1), and also of diffusive layer thickness (0.64–2.14nmm) and deployment time (3–168 h).
