摘要： A new solid phase extraction sorbent, based on poly(methacrylic acid) brushes-containing coordination polymer networks on monolith, was in-situ synthesized in a commercial syringe filter via surface grafting. Extraction of twenty model analytes, including nine sulfonamides, eight steroid hormones, and three quinolones, could be efficiently achieved by the monolithic hybrid filter due to multi-interactions. Through simple filtering steps, fast extraction (60 s of adsorption and 60 s of desorption) could be achieved. Furthermore, the monolithic hybrid filter was used to analyze the model compounds in chicken meat samples in combination with ultra-performance liquid chromatography-tandem mass spectrometry. Compared with other adsorption sorbents in reported literatures, the proposed monolithic hybrid filter allowed for shorter purification time, simplified sample pretreatment procedure, and comparable LODs and LOQs of 0.1-3 mu g kg(-1) and 0.4-10 mu g kg(-1), respectively. The recoveries for all analytes ranged from 83.9% to 103% with inter-day relative standard deviation lower than 10%. The results demonstrated that the developed analytical method was highly efficient and operationally convenient, and had a great potential for high throughput analysis of multi-residues.
