M. Hidalgo et al., SURFACE-ENHANCED RESONANCE RAMAN-SPECTROSCOPY OF 2-PYRIDYLHYDRAZONE AND 1,10-PHENANTHROLINE CHELATE COMPLEXES WITH METAL-IONS ON COLLOIDAL SILVER, Analytica chimica acta, 318(2), 1996, pp. 229-237
Surface-enhanced resonance Raman spectra (SERRS) of the complexes PAPH
-Co(II), PAPH-Ni(II), PAPH-Fe(II), and PHEN-Fe(II) (PAPH = 2-pyridine
carboxyaldehyde 2-pyridylhydrazone and PHEN = 1,10-phenanthroline) ads
orbed on silver colloid have been studied. Differences among SERS spec
tra of ligands and SERRS spectra of complexes have been investigated.
Ultra-sensitive methods for metal determination with limits of detecti
on at the ng ml(-1) level are presented.
