Studying the Photocatalytic Degradation of Tri-n-Butyl Phosphate Using Nano Nd-Doped TiO2
Photocatalytic method was used as an efficient and simple way for degradation of tri-n-butyl phosphate (TBP). In contrast to other methods, in this method the mineralization occurs and no twin pollution is generated. Nd doped TiO2 was synthesized via sol gel process and characterized by XRD and TEM tecniuqes. Then it was used as photocatalyst for TBP degradetion. It was found that the solution ...
متن کاملEquilibrium Study on Reactive Extraction of Acetic Acid with Tri-n-butyl Phosphate in N-hexane
Extraction of carboxylic acids from dilute aqueous solution using traditional solvents such as ketones, alcohols, ethers, and ester is inefficient because the distribution ratio is rather low. Reactive extraction which exploits reversible chemical complexation is an effective separation process for extraction of carboxylic acids from aqueous streams such as fermentation broths and wastewaters. ...
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 کاملHomogeneous 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 کاملIntermolecular structure in tri-n-butyl phosphate/n-octane mixtures: a molecular dynamics simulation study
Tri-n-butyl phosphate (TBP) is an important extractant for heavy metal ions. The microscopic structure of TBP/n-octane mixtures as a function of concentration of TBP is examined through atomistic molecular dynamics simulations. A weak association between TBP molecules both in pure TBP as well as in the octane solution is established. In dilute TBP/n-octane solutions, TBP molecules are inhomogen...
