摘　　要：用荧光分光光度计测定浸泡粉煤灰海水中多环芳烃（ＰＡＨｓ）的含量，用反相高效液体色谱紫外检测器／荧光检测器测定海水浸泡前后粉煤灰中多环芳烃。热电厂粉煤灰在海水中２种溶出结果表明，其粉煤灰在海水中的静态溶出和吸附可逆，ＰＡＨｓ的溶出极少。热电厂粉煤灰倾倒于海水中溶出的多环芳烃对海洋环境污染甚微。Releasing of PAHs from coal-ash in seawater was determinated by fluorescence spectrophotometer.The amounts of PAHs from coal-ash soaked before and after in seawater were also analysed by reversed high performance liquid chromatography With UV or fluorescence detectors.The results show that the static state releasing and adsorption of PAHs from coal-ash in seawater are reversible,releasing of PAHs is pool,and PAHs in the fine coal-ash dumped into sea from heat and power plant have little effect to the marine environment.
