Covalent triazine framework-1 as adsorbent for inline solid phase extraction-high performance liquid chromatographic analysis of trace nitroimidazoles in porcine liver and environmental waters
Covalent triazine framework-1 (CTF–1) was used for nitroimidazole extraction. CTF-1 has high extraction efficiency (87%–98%) and adsorption capacity. In-line SPE-HPLC was developed for the analysis of nitroimidazoles with low LODs. CTF–1 was suitable for aromatic compounds in environmental and biological samples.
