Abstract
Earlier it was demonstrated that surface-enhanced Raman spectroscopy (SERS) of cationic-coated silver substrates could successfully detect nitrate and sulfate in the parts-per-billion to parts-per-million concentration range. However, these cationic coatings also interact with chloride ion. In this paper, the magnitude of the chloride ion interference is examined. To elimi nate the interference, we explore the use of selective ionophores and solid -phase extraction (SPE).
