Rhodium Determination by Atomic Absorption Spectrometry Using the Nitrous Oxide-Acetylene Flame
Abstract:A study of the interferences encountered in determining rhodium in aqueous solutions by atomic absorption spectrometry is described. In this study, solutions containing rhodium and varying concentrations of a number of the more common elements and acids were aspirated into air–acetylene and nitrous oxide–acetylene flames. It was found that very serious interferences were encountered with the air–acetylene flame, while the nitrous oxide–acetylene flame was essentially free from such interferences. Optimum excitation parameters and the precision of replicate analyses are presented.
