Tóm tắt

In this paper, a novel robust TFPA-TTA-COF coating with nano pores was grafted to the gully-like surface of stainless steel fibers (GS-SSF). The GS-SSF were prepared using a two-step electrochemical etching method, and the covalent organic framework (COF) TFPA-TTA-COF coating was chemically bonded to the gully-like surface via in situ growth. The prepared metal fibers were applied as the headspace solid-phase microextraction (HS-SPME) fibers and combined with gas chromatography (GC) to develop a detection method for phenolic compounds (PCs) in water. The developed method gave the limits of detection (S/N = 3) from 0.07 µg·L
