Preparation of microporous organic polymer-based solid phase microextraction fiber and application to the determination of organochlorine pesticides


Abstract:
In the present work, a microporous organic polymer (MOP) was prepared with 1,3,6,8-tetrakis(p-formylphenyl)pyrene and melamine as monomers. The MOP material was adhered on a stainless steel fiber for headspace solid phase microextraction (HS-SPME). By combining with gas chromatography-electron capture detection, an online method was developed for the determination of organochlorine pesticides (OCPs) in rice samples. Four experimental parameters affecting the preconcentration efficiency were investigated in details. Under the optimum experimental conditions, extraction temperature of 80℃, extraction time of 25 min, NaCl mass concentration of 200 g/L, and desorption time of 6 min, high enrichment factors of 115-318 were achieved. The MOP-based fiber exhibited good linearity for OCPs in the range of 0.05-50 μg/kg. The detection limits ranged from 2.4 ng/kg to 11.3 ng/kg with relative standard deviations of 1.3%-13.1% for the same fiber and 2.3%-13.6% for different fibers. The developed method was proved to be simple and rapid and to be applied to the determination of trace amount of OCPs in rice samples.
