摘要
建立了芴、咔唑、苯并[α]芘和茈四组分同时测定的导数恒能量同步荧光分析法,并对其优越性进行了比较说明。该法简便快速,无需对混合物进行分离,只需一次扫描,就可实现这四组分的同时鉴别和定量测定。将该方法应用于河水样、自来水样和大气飘尘样的分析,取得了良好的效果,回收率分别为90.0%-108.0%,90.0%~104.0%和90.0-102.0%。
A new method of derivative constant-energy synchronous fluorescence (CESF) spectroscopy for the simultaneous determination of fluorene, carbazole, benzo[α]pyrene and perylene was developed. The comparison and explanation of its performance are presented. The derivative CESF spectra are apparently more structured than the direct CESF. The scanning of derivative CESF is more effective than derivative constant-wavelength synchronous fluorescence spectroscopy. By using this method, real samples (tap water, seawater and airborne particulates) were determined directly and good results were obtained. The recoveries in tap water, seawater and airborne particulates were 90.0%-108.0%, 90. 0%-104.0% and 90.0%-102.0% respectively.
