THE SOLVENT EXTRACTION OF NITROSYLHUTHENIUM BY TRILAURYLAMINE IN NITRATE SYSTEMS

摘要

An investigation of the solvent extraction characteristics of the nitro and nitrato complexes of nitrosylruthenium in nitric acid-sodium nitrate aqueous media was conducted. As the organic extractant phase, a solution of trilaurylamine (TLA) in toluene was utilized.nIn addition to the usual process parameter variation type of experiment, a rapid dilution/type of experiment was used extensively to determine qualitative and semiquantitative results regarding the degree of extractability and concentration of the more extractable species of the nitrato complexes of nitrosylruthenium. It was found that the acids of the tetra-nitrato and penta-nitrato complexes were the more extractable species for that set of complexes and that the acid of the penta-nitrato complex was the more extractable of the two.
