Homogeneous liquid-liquid extraction of uranium(VI) using tri-n-octylphosphine oxide.
A simple and efficient method for the selective separation and preconcentration of uranium(VI) using homogeneous liquid-liquid extraction was developed. Tri-n-octylphosphine oxide (TOPO) and tri-n-butylphosphate (TBP) were investigated as complexing ligands, and perfluorooctanoate ion (PFOA-) was applied as a phase separator agent under strongly acidic conditions. Under the optimal conditions (...
متن کاملExtractive Properties of Tri-n-octylphosphine Oxide Towards Thorium (IV) and Europium (III) Ions in Aqueous Nitrate Media
Phosphoryl containing ligand tri-n-octylphosphine oxide (TOPO) in dichloromethane has been used as an extracting agent for tetravalent thorium and trivalent europium ions from their 1 M sodium nitrates. The equilibrium data reveal that both ions are extracted as the complexes at 1:3 metal/ligand ratio. The values of conditional extraction equilibrium constant (Kex) show the superior extract...

متن کاملRecovery of Nicotinic Acid from Aqueous Solution using Reactive Extraction with Tri-n-Octyl Phosphine Oxide (TOPO) in Kerosene
Nicotinic acid (also known as pyridine-3-carboxylic acid) is widely used in food, pharmaceutical and biochemical industries. The extraction of nicotinic acid by tri-noctylphosphine oxide (TOPO) with kerosene (diluent) is studied. The equilibrium experiments are carried out to investigate the effects of diluent, extractant (TOPO) composition and initial acid concentration on extraction efficienc...
متن کاملIntensification of Propionic Acid Separation from Aqueous Solution using Reactive Extraction with Tri-n-butyl Phosphate (TBP) Dissolved in n-Decane and 1-Decanol
Over the last three decades, there has been a resurgence of interest in large-scale production of fermentation chemicals due to the sharp increase in petroleum cost. So the potential role of a new energy efficient fermentation technology is receiving growing attention. Propionic acid is widely used in the food, pharmaceutical and chemical industries. Fermentation technology for the production o...
