Separation with solvent extraction of Cu(II), Hg(II), and Cr(III) from
aqueous solution using the ligend (HL) as a new extractant has been studied.
The new acyclic Schiff Base (HL) was synthesized by reaction of 5-bromosalicylaldehyde
with 2-(2-Am
inoethyl)pyridine. The structure of the new
compound (HL) was confirmed by using FT-IR spectra, 1H-NMR and 13CNMR
spectra and mass spectra (MS). The effect of chloroform and
dichloromethan as organic solvents in the metal extractions was investigated at
20oC by using UV-visible Spectrometry. The influence of pH, ligand
concentration, shaking time and ratio of aqueous-to-organic phases on
extraction yield was tested at 20oC. The extractability of the tested metal ions
were evaluated.
A new acyclic Schiff Base(II), containing nitrogen-oxygen donor atoms was
synthesized by reaction of 1,2-Bis (5-bromo-2-formyl-phenoxy) ethane with 2-
(2-Aminoethyl)pyridine and characterized. The liquid-liquid extraction of
transition metals such
as Cu+2, Cr+3 and Uranyl-picrate (UO2)+2 from aqueous
phase to the organic phase was carried out using the novel ligand. The effect of
chloroform and nitrobenzene as organic solvents on the metal extractions was
investigated at 20oC by using Atomic Absorption and UV-visible
Spectrophotometry. The influence of pH, ligand concentration, ionic strength,
shaking time and ratio of aqueous-to-organic phases on extraction yield was
tested at 20oC. The extractability of the tested metal ions were valuated.
