AN161: Determination of Metal Cyanide Complexes by Ion Chromatography with On-Line Sample Preconcentration and UV Absorbance Detection. Be the first to rate this application

determination metal cyanides


In this application note, an improved IC method is described for the determination of metal cyanide complexes in environmental waters. The metal cyanide complexes of silver, gold, copper, nickel, iron, and cobalt are separated on an anion-exchange column and quantified by measuring their absorbance at 215 nm. Sensitivity for most of the metal cyanide complexes is improved by over two orders of magnitude, compared to a direct injection, by preconcentrating metal cyanide complexes from a large sample volume onto a trap column before separation.
