A New and Sensitive Hydride Generation-Nanosilver Resonance Rayleigh Scattering Spectral Method for Trace Se (IV)

Article Preview

Abstract:

In HCl solution, the Se (IV) was reduced to SeH₂ by NaBH₄, and absorbed by solution of ethanol-AgNO₃. The Ag⁺ was reduced to nanosilver, which led to the resonance Rayleigh scattering (RRS) peak at 366 nm increased. Under the selected conditions, the RRS intensity at 366 nm was linear to the concentration of Se (IV) in the range of 0.05-2.0 μg/mL, a detection limit of 0.02 μg/mL. The proposed method was applied to detect Se (IV) in water samples, with satisfactory results.
