摘要
研究了有机溶剂、无机盐、尿素对萘胺-β-环糊精及其衍生物荧光体系的影响,发现它们对萘胺有荧光增强效应。
The effects of organic solvents, urea and inorganic salts on fluorescence intensities of naphthylamine in the presence of β-cyclodextrin and its derivatives were investigated in detail. The fluorescence enhancements of β-cyclodextrin and its derivatives for naphthylamine were improved by organic solvents, urea and inorganic salts. The sequence of fluores- cence enhancements by inorganic salts on naphthylamine in β-cyclodextrin and its derivatives is as follows: NaF>NaCl>NaBr>NaI. The mechanism of the fluorescence enhancement of organic solvents, urea and inorganic salts for naphthylamine in the presence of β-cyclodex- trin or its derivatives was discussed.
