A covalent organic framework TPB-DMTP was physically coated onto the gully-like surface of stainless-steel fiber. The fabricated TPB-DMTP-coated fiber used to extract five phthalic acid esters (PAEs) prior GC-FID separation and determination in bottled tea beverages. developed SPME-GC-FID method gave limits detection (S/N = 3) from 0.04 µg·L-1 (DBP) 0.44 (BBP), with enrichment factors 268 (DEHP) 2657 (DPP). relative standard deviations (RSDs) built for inter-day fiber-to-fiber were 4.1-11.8% 2.3-9.9%, respectively. prepared fibers could stand at least 180 cycles without a significant loss extraction efficiency. successfully applied trace PAEs different beverages, recoveries 85.5% 115%.
