Abstract

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

新型沟槽型不锈钢纤维表面COF-TPB-DMTP纳米颗粒固相微萃取瓶装茶饮料中邻苯二甲酸酯。

将共价有机骨架TPB-DMTP物理涂覆在不锈钢纤维沟槽状表面。采用制备的tpb - dmtp包覆不锈钢纤维，对瓶装茶饮料中5种邻苯二甲酸酯（PAEs）进行GC-FID分离测定。SPME-GC-FID方法的检出限（S/N = 3）为0.04µg·L-1 (DBP) ~ 0.44µg·L-1 (BBP)，富集因子为268 ~ 2657 （DPP）。所建方法在日间和光纤间的相对标准偏差（rsd）分别为4.1 ~ 11.8%和2.3 ~ 9.9%。制备的tpb - dmtp涂层不锈钢纤维可以承受180次以上的循环萃取而不显著降低萃取效率。该方法可用于不同瓶装茶饮料中痕量PAEs的测定，回收率为85.5% ~ 115%。

期刊介绍： Nanomaterials (ISSN 2076-4991) is an international and interdisciplinary scholarly open access journal. It publishes reviews, regular research papers, communications, and short notes that are relevant to any field of study that involves nanomaterials, with respect to their science and application. Thus, theoretical and experimental articles will be accepted, along with articles that deal with the synthesis and use of nanomaterials. Articles that synthesize information from multiple fields, and which place discoveries within a broader context, will be preferred. There is no restriction on the length of the papers. Our aim is to encourage scientists to publish their experimental and theoretical research in as much detail as possible. Full experimental or methodical details, or both, must be provided for research articles. Computed data or files regarding the full details of the experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Nanomaterials is dedicated to a high scientific standard. All manuscripts undergo a rigorous reviewing process and decisions are based on the recommendations of independent reviewers.
