Mb. Gholivand et S. Khorsandipoor, Selective and efficient uphill transport of Cu(II) through bulk liquid membrane using N-ethyl-2-aminocyclopentene-1-dithiocarboxylie acid as carrier, J MEMBR SCI, 180(1), 2000, pp. 115-120
N-ethyl-2-aminocyclopentene-1-dithiocarboxylic acid is an excellent synthet
ic carrier for highly efficient and selective transport of Cu(II) ions thro
ugh a liquid membrane and has the ability to transport Cu(II) ions uphill.
In the presence of hydrazine sulfate as a reducing agent and thiocyanate as
a metal ion acceptor in the receiving phase and at the optimum pH of 1.5,
about 100% of copper was transported over a period of 1 h. The carrier can
selectively and efficiently transport Cu(II) ion from aqueous solutions con
taining other cations such as Mg2+, Ca2+, Co2+, Ni2+, Cd2+, Fe2+, Cr3+, Cr6
+, Zn2+, Mn2+, Pd2+, Pb2+, Hg2+, Sn2+, Fe3+. Al3+ and Ag+. (C) 2000 Elsevie
