Resonance Rayleigh Scattering Spectral Determination of Se Using NaH2PO2 as Reducer
Keyword(s):
In the HCl medium of 0.90 mol/L, Se (IV) was reduced by NaH2PO2and generated selenium nanoparticles, and there is a resonance Rayleigh scattering (RRS) peak at 588 nm. Under the selected conditions, with the increased of Se (IV) concentration, generated selenium nanoparticles increased, the resonance Rayleigh scattering peak intensity (ΔI588nm) at 588 nm was increased, and the ΔI588nmhad good linear relationship to Se (IV) concentration in the range of 0.1-1.5 mg/L, with a linear regression equation of ΔI588nm= 489.9C+ 9.0, the detection limit of 12.0 μg/L.
