Jc. Bermejo et al., Solvent extraction of Cu(II) by LIX 54-100 and its application to a solid supported liquid membrane system, J CHEM R-S, (10), 2000, pp. 479-481
The extraction of Cu(ll) by LIX 54-100 (beta -diketone) in lberfluid (keros
ene type diluent) from ammoniacal/ammonium sulphate solutions has been inve
stigated. The analysis of metal distribution data suggested the formation o
f CuR2 species in the organic phase with formation constant log K-ext= -6.1
5. The results obtained on Cu(ll) distribution have been implemented in a s
olid supported liquid membrane system, using H2SO4 solutions tag. 0.9 mol/l
) to strip the metal from the organic solution.
