Spectra of Resonant Luminescence and Double Scattering of Mercury(Ⅱ)-Thiocyanate-Victoria Blue 4R System and Their Analytical Application

Abstract

Abstract: This work studied the spectra of resonant luminescence(RL),double scattering(DS)and anti-double scattering(ADS)of the ion-association complex of[Hg(SCN)₄]^2- withVictoria blue 4R(VB 4R).The spectral characteristics,the effect factors and the optimum conditions of the reaction have been investigated.The quantitative relationships of the I_RL,I_ADS and I_DS to the concentration of mercury were established.Anew analytical method for determination of trace mercury(Ⅱ) was proposed.And we have a preliminary discussion on relative mechanism.

Key words: Resonant luminescence spectra, Double scattering and anti-double scattering spectra, Mercury, Thiocyanate-Victoria 4R system
