［中文文摘］建立了蒽和9,10二甲基蒽的同时恒能量同步荧光分析法。它们的恒能量同步荧光光谱和常规荧光光谱相比,分辨力明显提高。蒽和9,10二甲基蒽的线性范围分别为0～2μg·mL-1和0～5μg·mL-1,检出下限分别为22ng·mL-1和17ng·mL-1,相对标准偏差不大于2%。水样中蒽和9,10二甲基蒽的回收率为85%～103%。该方法简便快速,无需预分离。［英文文摘］ A new method of constant2energy synchronous fluorimetry to determine anthracene and 9 ,102dimethylanthracene simulta2 neously is suggested. The spectral resolution of the constant2energy synchronous fluorescence spectra of these two compounds was much higher than that of conventional spectra. The linear ranges for anthracene and 9 ,102dimethylanthracene were 022μg·mL - 1 and 025μg ·mL - 1 respectively. The detection limits of anthracene and 9 ,102dimethylanthracene were 212 ng·mL - 1 and 117 ng·mL - 1 respec2 tively , and the relative standard deviation was less than 2 %. When the new method was used for the determination of anthracene and 9 ,102dimethylanthracene in water samples , the recoveries were in the range of 85 % to 103 %. This method has proved to be simple and rapid.
