摘要
本文研究[Hg（SCN）4]2-络阴离子与罗丹明B和罗丹明6G离子缔合络合物的二级散射（DS）和“反二级散射”（ADS）光谱，考察了光谱特征、影响因素及适宜的反应条件；确定了DS和ADS强度与溶液中汞（Ⅱ）浓度的关系；提出了用ADS法测定痕量汞的新的高灵敏度分析方法，并对有关机理作了初步的探讨。
This work studied on the spectra of double scattering and "antidouble scattering"of the ion-association complexes of [Hg (SCN )4]2- with basic xanthene dyes such as rhodamine B and rhodamine 6G. The spectral characteristics, the effective factors ai1d optimum conditions have been investigated. The relation between the intensity of double scattering light and the concentration of Hg(Ⅱ ) was established. A new and high sensiitive way for determination of trace amounts of Hg(Ⅱ ) by the ADS method was proposed.
