چکیده
The use of liquid-liquid extraction for the separation of tantalum from niobium was demonstrated. Tantalum and niobium spectrographically free of each other were prepared in quantity on a continuous basis.

Green extraction of Niobium and Tantalum from Kenticha Tantalite ore using 1-Ethyl-3-Methyl Imidazolium Chloride ionic liquid
The decomposition of the Ethiopian Kenticha tantalite ore was studied using the KOH fusion and H2O leaching system at 400 0C for a 1 h reaction time. The experimental results obtained showed that 27 wt% of Ta2O5 was mainly transformed into insoluble KTaO3, not to be KNbO3, and as well, into the dissolved liquor containing 94.73 vol% of Nb2O5 and 75.80 vol% of Ta2O5. The observations, supported ...
متن کاملPhysical separation of amphiprotic-polar aprotic solvents for simultaneous extraction and clean-up of clomiphene from plasma before liquid chromatographic analyzes
An efficient and quantitative two phase freezing (TPF) method coupled with high performance liquid chromatography and UV-Vis detector was developed for the extraction, clean up and determination of clomiphene citrate (CLC) in plasma samples. The separation of two miscible solvents by TPF method permits that the CLC was efficiently removed from proteins and transferred into the relative aprotic ...

Extraction-separation of Eu(III) and Th(IV) ions from nitrate media into the ionic liquid 1-hexyl-3-methylimidazolium hexafluorophosphate by a phosphorylated salen extractant, bis(chlorophosphoryle)decahydro-2,4-di(2-hydroxyphenyl)benzo[d][1,3,6]oxadiazepine (DPO), is investigated. It is found that Eu(III) ions are extracted via a solvation mechanism, and the extraction of Th(IV) i...
متن کاملApplication of solvent extraction for the removal of amoxicillin drug residues in environmental waters
In this study, extraction of amoxicillin (AMOX) ions from aqueous solution by liquid-liquid extraction (LLE) was investigated. The LLE process by response surface methodology (RSM) was carried out based on central composite design (CCD). The organic phase consisted of extractant and toluene as diluent. In this process, triethylamine (TEA), di-2-ethylhexyl phosphoric acid and mono-2-ethylhexyl p...
