Non-aqueous atomic-absorption spectrophotometric analysis of organonickel complexes by a ligand exchange method

Abstract

A procedure is described in which diethylammonium diethyldithiocarbamate is used to complex nickel in a mixed organic solvent, thus eliminating interferences due to different bonding. The interferences can also be removed by using a nitrous oxide-acetylene flame and a method has been devised that requires the use of only a single solvent for dissolution. The ligand exchange method should have wide application in the elimination of bonding interferences.
