ABSTRACT:
A method of selectively separating lead ions from metal ions-containing aqueous liquid by contact with a solution containing a polyether derivative dissolved in a water-insoluble organic solvent and serving as an ionophore or carrier for lead ions. The polyether derivative is a compound expressed by the general formula: ##STR1## wherein R.sub.1 and R.sub.2 stand independently from each other for a hydrogen atom or an alkyl group and n is an integer of 2 or 3.
