Development of a Novel SPME Coating for Efficient Extraction of Organochlorine Pesticides in Liquid Dairy Products

Journal of Agricultural and Food Chemistry, Год журнала: 2024, Номер 72(37), С. 20679 - 20689

Опубликована: Сен. 6, 2024

A sensitive and accurate analysis of organochlorine pesticide (OCP) residues in dairy products poses a significant challenge. Herein, novel covalent organic polymer, Azo-COP-1, was synthesized for the enhanced extraction OCPs products. The solid phase microextraction fiber coated with Azo-COP-1 demonstrated excellent performance via hydrogen bonding, halogen π-π stacking, electrostatic interactions. Coupled gas chromatography-electron capture detection, we developed facile reliable method detecting six types low limits detection (2.0-400 pg g

Functionalization of Covalent Organic Frameworks with Cyclopentadienyl Cobalt for C2H2/CO2 Separation

Angewandte Chemie, Год журнала: 2024, Номер unknown

Abstract Emerging covalent organic frameworks (COFs) have received great attention for their unique features, but the limited building blocks restrict structural diversity and performance exploration. Reticular chemistry provides guidance expansion regulation of COFs. Herein, we constructed two novel two‐dimensional (2D) COFs functionalized with cyclopentadienyl cobalt, denoted as UPC‐COF‐1 UPC‐COF‐2, via [4+2] imine condensation diamine different length. Theoretical simulations combined experimental results reveal that shorter blocks, narrower pore sizes, stronger host–guest interactions has better C 2 H /CO separation performance. In addition, can maintain stability in presence water vapor methane impurities. This work a new evidence isoreticular modular tunable blocks.
