Abstract in English
New Schiff base (H2L) containing nitrogen-sulfur-oxygen atoms was
synthesized by reaction of α,α'-bis(5- Bromo-2-carboxyaldehyde phenoxy)-1.4-
xylene with aminothiophenol. Transport of copper ion across a bulk
chloroform membrane containing Schiff base ligand (H2L) as carrier has been
studied. The parameters influencing the transport efficiency such as
composition of receiving phase, pH of the feed phase, carrier concentration in
the membrane, EDTA concentration in the receiving phase, effect of
temperature and time dependency of the process were studied and discussed.
The amount of copper transport through the liquid membrane after 48 min.,
arrived to 100% at temperature 58°C.
