Abstract

This paper proposes a simple HPLC method for the determination of polycyclic aromatic hydrocarbons (PAHs) in water, wine and beer. Samples were purified by PAH collection in solid-phase extraction (SPE) and analysed by reversed-phase HPLC (Supelcosil LC-PAH column from Supelco). For the beer sample, recoveries amounted to 28% for naphthalene and varied from 57% to 103% for the other PAHs; results are quantitative starting from fluoranthene (FI, the seventh component eluted). Almost all the beer and wine samples showed the presence of benzo(b)fluoranthene (BbF), benzo(k)fluoranthene (BkF), benzo(a)pyrene (BaP), benz(ghi)perylene (BghiP) and indeno(1,2,3-cd)pyrene (IP), and in some cases there were traces of FI, benzo(a)anthracene (BaA) and dibenz(ah) anthracene (DBahA). Total contents of PAHs ranged from trace amounts to 0.72 ppb. Traces of BbF, BkF, BaP, BghiP and IP were also found in the wine samples.

摘要

本文提出了一种简单的高效液相色谱法,用于测定水、葡萄酒和啤酒中的多环芳烃(PAHs)。样品通过固相萃取(SPE)收集PAHs进行纯化,并采用反相高效液相色谱法(使用Supelco公司的Supelcosil LC-PAH柱)进行分析。对于啤酒样品,萘的回收率为28%,其他PAHs的回收率在57%至103%之间;从荧蒽(FI,洗脱的第七种成分)开始,结果是定量的。几乎所有啤酒和葡萄酒样品都显示存在苯并(b)荧蒽(BbF)、苯并(k)荧蒽(BkF)、苯并(a)芘(BaP)、苯并(ghi)苝(BghiP)和茚并(1,2,3-cd)芘(IP),在某些情况下还存在痕量的FI、苯并(a)蒽(BaA)和二苯并(ah)蒽(DBahA)。PAHs的总含量范围从痕量到0.72 ppb。在葡萄酒样品中也发现了痕量的BbF、BkF、BaP、BghiP和IP。
