摘　　要：多环芳烃（PAHs）具有较高的荧光量子产率，非离子表面活性剂对其有增溶增敏作用。建立了吐温-80（TW-80）胶束增敏水中溶解态蒽（ANT）的直接荧光分析方法。所建立方法测定蒽的线性范围为1．6833×10^-8～1．29×10^-6mol／L，检出限为1．07×10^-8moil/L。该方法灵敏，应用于自来水样、江水样、湖水样的分析，取得了良好的效果，江水中回收率为94．6％-109．5％，湖水中回收率为90．5％～106．9％，自来水中回收率为86．9％～111．7％。为预测和治理水污染提供了一种灵敏、快速且简便的测试手段。As PAHs has a high Photoluminescent （PL） quantum yield and the solubilization and sensibi- lization effect of Nonionic surfactants on PAHs, a spectrofluofimetry has been established for Tween-80 （TW-80） micellar sensitization of dissolved Anthracene（ANT） in water. The linear ranges for the deter- mination of dissolved Anthracene was 1. 6833 ×10^-8- 1.29×10^-6 mol/L, the detection limits was 1.07 ×10^-8mol/L. The method was highly sensitive. By using this method, real samples（tap water, fiver-wa- ter,lake-water） were determined directly and good results were obtained. The recovery of fiver-water was 94.6% - 109.5%, the recovery of lake-water was 90.5% - 106.9% ,and the recovery of tap-water was 86.9% -111.7%. The method is rapid, sensitive, and simple to forecast and manage the pollution of water.
