Abstract

The double scattering (DS) and anti-scattering (ADS) spectra of the ion-association complexes of [Hg(SCN)4]^2^- with the basic triarylmethane dye such as crystal violet (CV), malachite green (MG), brilliant green (BG), and iodide green (IG), their spectral characteristics and effective factors, and the optimum conditions of the reaction were investigated. The relation between the intensities of DS and ADS light and the concentration of mercury (II)was established. A new and highly sensitive way for the determination of mercury(II) by the ADS spectra has been proposed. Preliminary dicussed the mechanism of the reaction and the reasons of the change in the double scattering.
