Abstract: The liquid membrane transports of K+ions by p-tert-butylcalix arene as carrier are investigated by the bubbling pseudo-emulsion liquid membrane. This transport process is a protoncoupled transport with a coupled flow of protons in opposite direction. The driving force for the transport is the pHgradient between the source phase and the receiving phase. The selected transport for K+ion or Na+ion by p-tert-butylcalix[n]arene(n=4, 6, 8) as carriers are investigated.
