本文将十八烷基修饰的石墨烯(G-C18)复合材料用于中空纤维液相微萃取(HF-LPME).氯酚作为模型分析物,用来评价G-C18增强的HF-LPME方法的实用性。结果表明,2-氯酚(2-chlorophenol,2-CP)和3-氯酚(3-chlorophenol, 3-CP)在5.0-200.0ng/g浓度范围内,2,3-二氯酚(2,3-dichlorophenol,2,3-DCP)和3,4-二氯酚(3,4-dichlorophenol,3,4-DCP )在2.0-200.0ng/g浓度范围内线性良好。检出限(S/N=3)低于1.5ng/g,加标回收率为88%-108%。该方法简单、有效,己成功用于测定蜂蜜样品中氯酚残留。
