Abstract
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.
