AI Technical Summary
Existing detection methods are difficult to efficiently and cost-effectively separate and detect neonicotinoid pesticides from environmental water samples, and traditional adsorbents have small adsorption capacity and poor selectivity.
Conjugated microporous polymer materials were used as solid-phase extraction adsorbents, combined with high-performance liquid chromatography, and CMP materials were prepared via Sonogashira coupling reaction for the extraction, enrichment, and detection of neonicotinoid insecticides in environmental water samples.
It achieves efficient, simple, and low-cost detection of neonicotinoid insecticides, improves the specific surface area and selectivity of the adsorbent, simplifies the sample pretreatment process, reduces analysis time and cost, and provides good accuracy and reproducibility of the detection results.
