Reactive extraction is a promising technique for the recovery of carboxylic acid from dilute aqueous solutions. Reactive extraction requires a proper combination of extractant and diluent which provides higher capacity and selectivity. The recovery of propionic acid by reactive extraction (present i

The extraction and transport behaviour of uranium from nitric acid medium across a supported liquid membrane has been studied using di(2-ethylhexyl)isobutyramide as the carrier. The effects of experimental parameters such as nature of diluents, e.g., n-dodecane, benzene, chloroform, tert-butyl benze

Supercritical fluid extraction (SFE) of uranium and thorium from solid matrices was carried out employing CO2. Direct dissolution and extraction of oxides of uranium viz. UO2 and U3O8 was performed. UO2 and U3O8 powders (0.02–0.05 g) along with 2 ml of TBP–HNO3 complex were taken in extraction vesse

A solution containing oxalate complexes of rare earths, yttrium and iron (III) is obtained during the processing of wet process phosphoric acid for uranium recovery by solvent extraction. A process is described to recover oxalic acid from such a solution. The process is based on the conversion of ir
