摘　　要：研究了 [Zn(SCN) 4 ]2 - 络阴离子与罗丹明B和丁基罗丹明B离子缔合物的“反二级散射”光谱 ,考察了光谱特性、影响因素及适宜的反应条件 ;确定了反二级散射光强度与溶液中Zn 浓度的关系 ;提出了用反二级散射光谱法测定痕量Zn的高灵敏度分析法。In this work the spectra of antidouble scattering (ADS) of the ion association complexes of [Zn(SCN) 4] 2- with basic xanthene dyes such as rhodamine B and butylrhodamine B were studied. The spectral characteristics, the effective factors and optimum conditions have been investigated. The relationship between the intensity of antidouble scattering light and the concentration of Zn? was established. A new and high sensitive way for determination of trace amounts of Zn? by the ADS method was proposed.
