二氧化锆微球表面键合磺化交联聚苯乙烯固相萃取填料的制备及应用
Preparation and application of solid phase extraction packing of zirconia microsphere coated with sulfonated crosslinked polystyrene
摘要
Abstract
Zirconia microsphere was prepared by polymerization-induced colloid aggregation (PICA) method and carbon-carbon double bond was grafted onto its surface by titanic acid ester coupling reagent.Poly(styrene-divinylbenzene) was synthesized by free radical polymerization by using styrene,divinylbenzene and carbon-carbon double bond on the microsphere surface in solution system,so the polymer was coated on the microsphere surface.After the benzene ring of the polymer was sulfonated,the cation exchange packing for solid phase extraction (SPE) was obtained.The material was characterized by Fourier transform infrared spectroscopy,scanning electron microscope and X-ray energy dispersive spectroscopy.Three herbicides of mesotrione,atrazine and acetochlor in water were determined by the SPE cartridge coupled with high performance liquid chromatography (HPLC).In the range of 0.5-3.0 mg/L,the relationships between the peak areas and mass concentrations of mesotrione,atrazine and acetochlor were linear with the correlation coefficients of 0.993 6,0.992 5,0.991 9,respectively.The limits of detection were 5.41,6.72 and 13.4 μg/L for mesotrione,atrazine and acetochlor,respectively.The results showed that the zirconium dioxide microspheres coated with polymer have diameters in the range of about 6 to 8 μm,the SPE cartridges of which have high adsorption rate for the targets.关键词
