The study focused on the preparation and characterization of a novel hydrazone-based covalent triazine polymer (Hz-CTP), which showed promising performance in the extraction of herbicides and chlorophenols. Various characterizations demonstrated that the Hz-CTP possessed large surface areas, high porosity, and stability against high temperatures. The satisfactory results obtained from the extraction of model analytes suggest the potential application of CTPs in extraction processes.
The current study dealt with the preparation and characterization of a novel hydrazone-based covalent triazine polymer (Hz-CTP). The Hz-CTP was synthesized by using 2,4,6-tris(hydrazino)-1,3,5-triazine (THTA) -with a C-3 symmetry- as the knots and the terephthaldehyde -with a C-2 symmetry- as the linkers. The synthesized Hz-CTP was used in dispersive solid-phase extraction of four different triazine herbicides and also fiber-based head-space solid-phase microextraction of chlorophenols (CPs). A series of characterizations showed that the Hz-CTP possessed large surface areas, high porosities, and high stability toward high temperatures. The adsorption performance and stability against moisture and thermal condition of the introduced CTP were examined by extraction trace concentration level of triazine herbicides and CPs in the water samples as model analytes. Triazine herbicides and CP analytes were determined with high-performance liquid chromatography coupled with UV-Vis detector and gas chromatography-flame ionization detector, respectively. Satisfactory results were achieved and prove the CTPs potential application in extraction.
