Resumo: | The uphill transport of Ag+ through a chloroform bulk liquid membrane containing meloxicam as an ion carrier was studied. Different experimental conditions for the increasing selectivity, sensitivity and kinetics of transport, e. g., the effect of meloxicam concentration in the chloroform membrane phase, pH of donors and acceptor phases, types and concentration of various stripping agents were examined. In the presence of thiocyanate as a suitable stripping agent in the acceptor phase, the amount of silver transported across the liquid membrane after 120 min was 97.8 ± 1.2%. The selectivity and efficiency of Ag+ transport from the aqueous solution containing other cations, such as: Co2+, Cr3+, Ni2+, Cd2+, Mn2+, Cu2+, Pb2+, Ca2+, Mg2+ and Zn2+ were investigated. Except Cr3+ and Pb2+ ions, none of the cations used interfere the silver transport, even at a Mn+/Ag+ molar ratio of 500. The interfering effect of the two mentioned cations was diminished in the presence of EDTA at pH 6. |
