建立了咔唑、1,2-苯并蒽、苯并[a]芘和2,3-苯并蒽四种多环芳烃同时快速测定的恒能量同步荧光分析法.选择能量差Δυ-=1400cm-1,仅需一次扫描,就可同时鉴别和定量测定四种多环芳烃.四种多环芳的线性范围依次为0.5-300ng·mL-1、0.2-250ng·mL-1、0.05-50ng·mL-1和0.5-350ng·mL-1,检出限在0.0046-0.023ng·mL-1之间.该方法简单快速、灵敏度高,无需对多环芳烃混合物进行预分离,可用于实际水样的直接分析,效果良好,回收率为83.0%-105.3%.
The simultaneous energy measurement of simultaneous determination of carbazole, 1,2-benzanthracene, benzo [a] pyrene and 2,3-benzanthracene was carried out simultaneously. The energy difference Δu- = 1400cm -1, only one scan can simultaneously identify and quantitative determination of four polycyclic aromatic hydrocarbons.The four polycyclic aromatic linear range of 0.5-300ng · mL -1,0.2-250ng · mL-1, 0.05-50ng · ML-1 and 0.5-350 ng · mL-1, with the detection limit of 0.0046-0.023 ng · mL-1.The method is simple, rapid, sensitive and does not require pre-separation of the PAHs mixture and can be used for the actual water The kind of direct analysis, the effect is good, the recovery rate was 83.0% -105.3%.
