Surface-Enhanced Raman Scattering Determination of Trace Phenanthroline Using Aggregated-Nanosilver as Substrate

Article Preview

Abstract:

Using PEG10000 and sodium citrate as stabilizer, sodium borohydride as reducing agent, a stable nanosilver sol had been prepared. In pH 6.0 Na₂HPO₄- NaH₂PO₄ buffer solution and in the presence of NaCl, a stable nanosilver aggregates were formed. Phenanthroline (Phen) adsorbed on the aggregated-nanosilver surfaces resulting in a surface-enhanced Raman scattering (SERS) peak at 1450 cm^-1observed, and the SERS intensity was enhanced with the concentration of Phen was between 1.25×10^-10 mol/L and 2.5×10^-9 mol/L. Based on these, a new sensitive SERS method has been proposed for the determination of trace Phen in the synthesis of samples, with satisfactory results.
