Hydroxyl Group-Enriched Microporous Organic Network for Ultrasensitive Solid-Phase Extraction of Triazine Herbicides : Experiment and Dft Calculation on Adsorption Behavior
Triazine herbicides are a category of key and broad-spectrum herbicides in agricultural crops. However, their unintended and excessive use has caused irreparable damage to environmental and agro-food safety concerns, thus harming human health. Herein, we report on a new hydroxylated microporous organic network (OH−MON) with a permanent micropore of 1.72 nm, high surface area, and high stability, synthesized by simple Sonogashira–Hagihara polymerization. When utilized as an advanced solid-phase extraction adsorbent for efficient adsorption of triazine herbicides, this established analytical approach showed an ultra-low detection limit (0.03−0.15 ng∙L -1 ), and a satisfactory reproducibility attributable to the generated rich selective hydrogen-bonding groups on the highly accessible inner skeleton, as demonstrated by the theoretical calculation and selectivity test. This study suggested the enormous practical application potential of OH−MON for preconcentration and detection of triazine herbicides in a complex matrix
