咔唑、蒽和苝的同时恒能量同步荧光法分析

Simultaneous Determination of Carbazole,Anthracene and Perylene by Constant Energy Synchronous Fluorimetry

建立了咔唑、蒽和苝的同时恒能量同步荧光分析法。对方法的优越性进行了比较说明。实验是在自制带恒能量扫描多功能荧光分光计上进行的。咔唑、蒽和苝的检测限分别为1ng/ml、0.8ng/ml和0.5ng/ml,相对标准偏差不大于4.4％。

A new method of constant energy synchronous fluorimetry for the simultaneous determination of carbazole, anthracene and perylene has been developed on a self-made versatile spectrofluorimeter with the function of constant energy synchronous scanning, The comparison and explanation of its performance is presented. The detection limits of carbazole, anthracene and perylene were lng/ml, 0.8ng/ml and 0.5ng/ml respectively. The relative standard deviation was less than 4.4%.
