AU147: Direct Determination of Metal Cyanides by Ion Chromatography with UV Absorbance Detection
Description
Metal cyanide complexes are of environmental concern because they release cyanide upon dissociation. The metal cyanide complexes of silver, gold, copper, nickel, iron, and cobalt are separated on an IonPac AS11 column and quantified by measuring their absorbance at 215 nm. Use of the 2-mm AG11/AS11 column set provides different selectivity, lower eluent use, and better solvent compatibility than the AG5/AS5 column set featured in AN 55. The method was evaluated for reproducibility, linearity, accuracy, precision, and spike recovery from various matrices.| Market: | Environmental |
