Résumé
A heterocyclic hypercrosslinked polymer (Py-DMB HCP) was prepared by Friedel-Crafts alkylation reaction using pyrrole as monomer and p-dimethoxybenzene as crosslinker. The Py-DMB HCP was employed as an adsorbent for solid-phase extraction (SPE) of phenylurea herbicides (PUHs) and showed superior extraction performance. Thus, a sensitive analytical method for the determination of PUHs from soybean milk and tomato samples was established by combining Py-DMB HCP based SPE with high performance liquid chromatography. Under the optimal conditions, good sensitivity was achieved with the detection limits of 0.10-0.20 ng mL
