微乳液是由表面活性剂、助表面活性剂、油与水在适当比例下组成的无色、透明低粘度热力学稳定体系,它在光度法中的增敏作用已有报道。而有关微乳液增敏原子吸收法还未见报道。本文研究了阴离子型表面活性剂 SDS-正丁醇-正庚烷-水四组分构成的微乳液对钙原子化行为的影响。结果表明:在最佳工作条件下,该微乳液对原子 Microemulsion is a colorless, transparent and low viscosity thermodynamically stable system composed of surfactants, cosurfactants, oil and water in appropriate proportions. Its sensitizing effect in photometry has been reported. The microemulsion sensitized atomic absorption method has not been reported. In this paper, the effect of the anionic surfactant SDS-n-butanol-n-heptane-water microemulsion on the calcium atomization behavior was studied. The results show that: under the best working conditions, the microemulsion of atoms
