摘要: 提出了三维荧光光谱总体积积分法并应用于多环芳烃萘、芘、的同时测定,结果表明:三维荧光光谱总体积积分法不仅可以同时测定萘、芘、而且灵敏度(信噪比)较常规法分别提高22、33和26倍,同时并考察了积分区域对灵敏度的影响。

Abstract: Three-dimensional fluorescence spectrometry for simultaneous determination of polyaromatic hydrocarbons, naphthalene, pyrene and perylene,by measuring total fluorescence intensity was proved. The results show that the method could be used not only to simultanously determine above-mentioned polyaromatic hydrocarbons, but also to improve,the signal to noise ratio by 22, 33 and 26 folds, respectively. Meantime, the effect of the integration region had been studied.
