摘　　要：建立了以滤纸为基质的蒽和芘的固体表面荧光分析法(SSF)。考察了影响蒽、芘SSF强度的各种因素,包括滤纸的种类、待测样的烘干时间和烘干温度等。实验表明,蒽的线性范围为7×10-7—5×10-5mol/L,检出限为0.36ng/斑,加标回收率在89.5%—113.4%之间,相对标准偏差为4.89%;芘的线性范围为4×10-6—1×10-3mol/L,检出限为0.10ng/斑,加标回收率在83.5%—120.4%之间,相对标准偏差为4.96%。A paper-substrate solid surface fluorescence method for determinations of anthracene and pyrene was established, The factors that influence SSF intensity, including the kind of filter paper, drying-time and drying-temperature of sample, were investigated. The linear range for anthracene is from 7× 10^-7 to 5 × 10^-5 with detection limit of 0. 36ng/spot,recovery of 89. 5%- 113.4% and the relative standard deviation of 4.89 %. The linear range for pyrene is from 4 × 10^-6 to 1× 10^-3 with detection limit of 0. 10ng/spot, recovery of 83. 5 %-120. 4% and the relative standard deviation of 4.96%.
