| Abstract: | Resonance scattering(RS) spectra of Zn(SCN)42-with crystal violet were studied in pH 5.0 NaAc-HAc medium and Tween 80 solution.The affecting factors and the optimum conditions of the reaction were investigated.A new method for the determination of trace Zine based on the relationship between the resonance scattering intensity and the concentration of Zn2+ was established.The results showed that there was a good linear relationship between the resonance scattering intensity and Zn2+ concentration in the rang... |
