摘要
本文以芘为模型化合物，对滤纸基质室温磷光法的重原子进行选择，并研究了影响磷光强度的因素．在通氮气情况下，以十二烷基硫酸铊为重原子，测定了芘、芴、萘三种多环芳烃的室温磷光．实验结果表明：芘、萘、芴的最低检测限分别为１５ｎｇ、３０ｎｇ和３０ｎｇ，相关系数均大于０９９５，相对标准偏差均小于５％．
The influences of heavy atomic salts and other factors on filter paper substrate room temperature phosphorescence were investigated with pyrene as a mode compound The RTP values of pyrene, fluorene and naphthalene were determined by aerating N 2 and using TlDS as a heavy atomic salt The detection limits of pyrene, fluorene and naphthalene were 1 5ng, 3 0ng and 3 0ng respectively,the correlation coefficients were more than 0 995 and the RSD were less than 5%
