ABSTRACT Herein, an amino‐functionalized covalent organic framework was synthesized and accommodated in the pores of porous hollow fiber. In this context, tetra (4‐aminophenyl) porphyrin for preparing desired as extracting sorbent employed fiber solid‐phase microextraction tebuconazole propiconazole. With respect to amino groups as‐synthesized porphyrin‐based framework, device has ability establishing a hydrogen bond with selected model analytes. Under optimum condition, linear range method both analytes were estimated 0.5–200 µg L −1 (the coefficient determination 0.9962 0.9990 propiconazole). The limits detection propiconazole calculated 0.02 g 0.03 , respectively. quantification also two equal 0.07 0.08 intra‐ inter‐day relative standard deviations, which fell between 1.8% 4.7%, computed assess accuracy suggested approach. proposed used extraction tomato, cucumber, apple, cabbage, carrot, obtained results showed success determining these from target samples.

ABSTRACT Capillary electrochromatography (CEC) has attracted significant attention and gained considerable recognition in the field of separation science owing to its excellent efficiency. While numerous reviews on CEC have been published recent years, a comprehensive systematic summary typical synthesis strategies for electrochromatographic stationary phases their state‐of‐the‐art applications remains lacking. This review highlights advances (over past 3 years) representative (including chiral separation, microextraction‐coupled analysis, metabolomics, enzyme food analysis) monolithic open‐tubular CEC. The advantages limitations each methodology are critically analyzed present balanced evaluation. Additionally, this work outlines future prospects regarding development trends phase preparation methods evolving

ABSTRACT Covalent organic framework (COF) has been popularly utilized to prepare chromatographic stationary phases due its a great diversity of composition, unique structure, easy modification, and so forth. However, the irregular shape nanometer size scale most COF materials greatly hinders their direct utilization as column packing. Herein, poly (styrene‐divinylbenzene) loaded with p ‐phenylenediamine‐1,3,5‐triformylphloroglucinol nanoparticles that derived from ‐phenylenediamine 1,3,5‐triformylphloroglucinol microspheres are constructed by in situ growth method. Then, imine groups (styrene‐divinylbenzene)@ reduced amino followed quaternized. The characterized using SEM, Fourier transform infrared spectra, N 2 adsorption‐desorption experiment, According results, could perfectly combine possess good monodispersity functionality nanoparticles. customized exhibits separation properties for conventional anions, acids, carbohydrates.
