A Simple and Selective Nanocatalytic Resonance Rayleigh Scattering Spectral Method for the Determination of Trace Re

A Simple and Selective Nanocatalytic Resonance Rayleigh Scattering Spectral Method for the Determination of Trace Re

In the HCl medium, rhenium (VII) or Re nanoparticles exhibited strong catalytic effect on the slow Te particle reaction between Te(VI) and Sn(II) at 70°C. The product of formed Te particles shows two strong resonance Rayleigh scattering peaks at 778 nm and 540 nm. The RS intensity at 778 nm enhanced...
