N,N'-DI(8-QUINOLYL)GLUTARAMIDE EXHIBITING HIGHLY SELECTIVE AND EFFICIENT UPHILL TRANSPORT OF CU(II) THROUGH LIQUID MEMBRANES

N,N',-Di(8-quinolyl)glutaramide has been found to be an excellent Cu(II) carrier in the transport through a chloroform liquid membrane. It can selectively and efficiently transport Cu(II) from a weakly acidic aqueous solution containing Cu(II), Zn(II), Ni(II), and Co(II). Several N,N'-di(8-quinolyl)glutaramide derivatives and their analogues have been prepared for comparison of this transport ability, which largely depends not only upon the structure of the carriers, but also upon the transport conditions.
