固相萃取-微乳液相色谱法测定环境水体中的3种酚类化合物
Determination of three phenolic compounds in water samples by solid phase extraction with microemulsion liquid chromatography
摘要
Abstract
A method for the determination of phenol,bisphenol A (BPA),2,4-dichlorophenol in water samples based on solid-phase extraction with microemulsion liquid chromatography (MELC) was established.The water sample was acidified,and then cleaned-up by a C18 solidphase extraction cartridge.The separation was carried out on an Inertsil C18 (150 mm × 4.6 mm,5 μm) with a gradient elution using a microemulsion (consisting of 3.0％ sodium dodecyl sulfate (SDS),6.0％ butyl alcohol,0.8％ n-heptane,90.2％ (water +0.5％ acetic acid)) and acetonitrile as mobile phases at a flow rate of 1.0 mL/min and a detection wavelength of 280 nm.The detection limits (S/N =3) of phenol,BPA,2,4-dichlorophenol were 0.74,8.0,8.0 μg/L,respectively.Good linearities were achieved for the target compounds over the range of 0.1-10 mg/L.The spiked recoveries of three phenolic compounds in blank water samples were 82.7％,87.8％,82.6％ for phenol,BPA,2,4-dichlorophenol respectively.The recoveries of target compounds in real water samples ranged from 85.7％ to 113.2％.The developed method is simple,selective,sensitive and applicable for the analysis of environmental water samples.关键词
