Abstract:Conjugated microporous polymers (CMPs) have been widely used in various fields as a new class of porous materials. In this study, a quinoxaline-based CMP (BQP-CMP) was prepared and used as the coating in SPME for the extraction and enrichment of nine phthalate esters (PAEs) in juice, soya sauce, cooking wine, and blended edible oil samples. Several parameters affecting solid-phase microextraction (SPME) were optimized. The feasibility of the developed method was verified using real samples, which showed low LO… Show more
