Abstract
New Schiff base (N2O2) containing nitrogen–oxygen atoms was designed and synthesized by the reaction of 5-amino-2-methoxy-phenol with terephthaldialdehyde. Transport of copper ion across bulk chloroform membrane containing (N2O2) 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 stirring speed, effect of temperature and time dependency of the process were studied and discussed. The selectivity of the processes toward copper ions were tested by performing the competitive transport experiments on the mixture containing Pb2+, Ni2+, Cd2+, Zn2+ and Co2+ ions. The amount of copper transport through the liquid membrane after 90min was 99% at 25°C.
