| 摘 要： | 建立了用固相萃取-高效液相色谱-荧光检测法测定海水中多环芳烃的方法,优化了色谱条件和萃取条件。除苊不能用荧光检测器检出外,其余15种多环芳烃的空白加标回收率在64.5%(苯并g,h,i],茚并1,2,3-cd]芘)～88.7%(苯并a]蒽)之间,相对标准偏差(n=5)为4.9%(荧蒽,苯并b]荧蒽)～11.1%(苯并g,h,i],茚并1,2,3-cd]芘),方法的检出限在0.72(蒽)～14.10 ng/L(荧蒽)之间,基本上达到了痕量分析的要求。利用该方法测得青岛湾表层海水中多环芳烃的浓度在0.125(苯并k]荧蒽)～25.996 ng/L(萘)之间,但苯并a]芘未检出。 |

| Abstract: | A method using solid phase extraction-high performance liquid chromatography with fluorescent detection was established for the determination of polycyclic aromatic hydrocarbons in seawater;the chromatographic and extraction conditions were optimized.With exception of acenaphthylene which was not fluorescently detected,the recoveries of other 15 PAHs were between 64.5%(for benzo perylene and indeno 1,2,3-cd] pyrene) and 88.7%(for benzo a] anthracene),the relative standard deviations(n=5) ranged from 4.9%(... |
| Keywords: | solid phase extraction high performance liquid chromatography seawater determination of polycyclic aromatic hydrocarbons |
