Solvent Extraction of Tellurium from Chloride Solutions Using Tri-n-butyl Phosphate: Conditions and Thermodynamic Data
The extractive separation of tellurium (IV) from hydrochloric acid media with tri-n-butyl phosphate (TBP) in kerosene was investigated. The dependence on the extraction of tellurium species, concentrations of tellurium and TBP, extraction time and stage, organic/aqueous ratio, and interferences from coexist metallic ions were examined and are discussed. Besides, the stripping agent and strippin...
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 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 کاملStudying 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 کاملExtraction of moderate oxidation state technetium species between 30 % tri-n-butyl phosphate and H2SO4/HNO3
The extraction of technetium species at oxidation state lower than +7 has been examined in sulfuric and sulfuric/nitric acid solutions using UV-Vis spectroscopy and optically transparent thin layer cell (RVC-OTTLE). Soluble Tc(III), TcO2+ and [Tc2O2]3+ species with absorption bands at 420-450, 400, and 502 nm, respectively, were detected as products of pertechnetates electroreduction. The distr...
