摘要(Abstract):
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。
