Abstract
The Te particles appear two strong resonance Rayleigh scattering peak at 778 nm and 540 nm. In the HCl medium at 70 oC, rhenium (VII) or Re nanoparticles catalyze the Sn(II) reduction of Te(VI) to form Te particles. The RS intensity at 778 nm enhanced linearly with Re concentration. The enhanced RS intensity was linear Re concentration in the range of 0.01-2.0 nmol/L, with a detection limit of 0.005 nmol/L Re. This method was applied to analysis of Re in real sample, and the results were agreement with that of the spectrophotometry
