摘要
本文提出,适当配比的β-环糊精(β-CD)和十二烷基硫酸钠(SDS),对4,5-苯并苤硒脑(记作Se-DAN)有协同增敏作用,可以不经环己烷萃取的步骤,在水溶液中直接荧光测定痕量硒。
A proper mixture of β-cyclodextrin and sodium dodecylsulfate in aqueous solution was found to show a synergistic enhancement to the fluorescence intensity of 4, 5-benzopiaselenol. The determination of trace selenium can be carried out directly in aqueous solution.
