Triazine-based covalent porous organic polymer for the online in-tube solid-phase microextraction of polycyclic aromatic hydrocarbons prior to high-performance liquid chromatography-diode array detection

Triazine-based covalent porous organic polymer for the online in-tube solid-phase microextraction of polycyclic aromatic hydrocarbons prior to high-performance liquid chromatography-diode array detection

A triazine-based covalent organic porous polymer (COP) was synthesized from the monomers 1,3,5-triphenylbenzene and tricyanogen chloride through the Friedel-Crafts response and characterised intimately utilizing Brunauer-Emmett-Teller evaluation, X-ray photoelectron spectroscopy, elemental evaluation, and scanning electron microscopy, which confirmed that the COP had a tough floor and appropriate extraction web site. It was then employed in in-tube …
