Determination of 15 Phthalate Esters in Drinking Water by Solid Phase Extraction-Ultra Performance Liquid Chromatography-Tandem Mass Spectrometry
摘要
Abstract
A method of solid phase extraction coupled with ultra performance liquid chromatography-tandem mass spectrometry ( SPE-UPLC/MS/MS) was developed for the determination of 15 phthalate esters. Drinking water samples were concentrated by C18 SPE cartridge. The fifteen phthalate esters were separated on a phenyl column with gradient elution using methanol and water as mobile phases. Multiple reaction monitoring ( MRM) acquisition under positive ion mode was performed. The external matrix standard solutions were used for the quantitative determination. The linear range of Di-n-butyl phthalate was 0. 63-1000 μg/L. The other 14 phthalate esters showed good linearity in the range of 0 . 002-500 μg/L with the correlation coefficients more than 0. 9970. The limits of quantification ( LOQ) were 2. 2-632 ng/L. The spiked recoveries ranged from 81 . 3% to 109%. The relative standard deviations were less than 14%.关键词
