摘要
本文试图用化学增感模型解释FAAS中表面活性剂的作用。如表面活性剂亲水端与分析离子电荷相反,雾化时便聚积在分析离子周围形成反转胶束,保护分析元素不受其他离子干扰,胶束分解产生的还原性提高了分析元素的原子化效率,产生增感作用。
A new chemical enhancement model which attempts to explain the effects of surfactant on FAAS is proposed. Surfactant molecules accumulate again to form a reversed micelle in nebulization process, analysis element is protected from interference of foreign ions, and atomization efficiency is elevated by reduction of decomposition products of micelle in flame, if hydrophilic ends of surfactant molecules are opposite in charge to the analysis ions.
