- <p>The research on transport of Cr3+, Cd2+, Pb2+, and Ag+ through bulk liquid membrane using p-tert-butylcalix[4]arene-tetraethylester as ions carrier has been conducted. The aims of this research are determine optimum condition, efficiency, and selectivity of transport of the ions carriers to those ions. Both optimum condition and efficiency of transport were obtained by determination of transported ions concentration with variation source phase pH, ionic carrier concentration, nature of stripping agent in target phase, and transport time. The ion transport selectivity of ion carrie was obtained from experiments of equimolar mixture ions transport competition. Amount of Cr3+, Pb2+, Cd2+, and Ag+ transported across liquid membrane was about 0, 10, 10 and 50 % respectively after being transported for 24 hours, except for Pb2+ (48 hours). The ion carrier is selective for Ag+ where separation factor to Cd2+ was 16, that to Pb2+ was 43, and that for Cr3+ was infinite above on its optimum condition.</p>
