Resonance Rayleigh Scattering Spectral Determination of Se Using NaH₂PO₂ as Reducer

Abstract:

In the HCl medium of 0.90 mol/L, Se (IV) was reduced by NaH₂PO₂ and 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 (ΔI_588nm) at 588 nm was increased, and the ΔI_588nm had good linear relationship to Se (IV) concentration in the range of 0.1-1.5 mg/L, with a linear regression equation of ΔI_588nm= 489.9C + 9.0, the detection limit of 12.0 μg/L.
