Solvent Extraction of Gd from Chloride Solution with PC88A

Solvent extraction and stripping of zinc from synthetic chloride solution in presence of manganese and cadmium as impurities

In this research work, solvent extraction and stripping of zinc ions from a Zn-Mn-Cd-bearing solution was investigated using D2EHPA as the extractant in a chloride medium. The efficiency of the extraction and stripping stages was evaluated separately, and different parameters such as the pH, extractant concentration, reaction temperature, and contact time were studied. Based on the results obta...

Solvent extraction of Gd(III) from perchlorate and nitrate media with mixtures of thenoyltrifluoroacetone and Benzo-15-Crown-5

The extraction of Gadolinium (Gd) from perchlorate and nitrate media in 1,2-dichloroethane(C2H4Cl2), carbon tetrachloride (CCl4) and chloroform (CHCl3) by mixtures of 2-thenoyltrifluoroacetone (HTTA) and a crown ether benzo-15-crown-5 (B15C5) is investigated.The composition of the extracted species is determined as Gd(TTA)3.nB15C5 (n=1 in nitratemedium and n=2 in perchlorate medium). The values...

Selective and Efficient Solvent Extraction of Copper(II) Ions from Chloride Solutions by Oxime Extractants

Oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (HL1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (HL2) were synthesized and characterized by conventional spectroscopic methods. Suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extr...
