Abstract
Surface - enhanced resonance Raman scattering of humic and fulvic acids from various sources adsorbed on silver sols were investigated. Only in acidic conditions, the strong SERRS spectra of humic substances were observed and these results revealed the disordered graphite structures of almost all the samples. The detection limits were 5 – 80 ug/L. Thus SERRS appears very promising in analysis and detection of humic substances in complex systems as well as real environment.Keywords
