文摘

Highly selective liquid membrane is proposed for EMEs of specific inorganic anions. Selectivity is obtained by modifying liquid membranes with a macrocyclic compound BU6. EME selectivity is directly proportional to association constants between BU6 and anions. Efficient EMEs of target anions are achieved at up to 100.000-fold excess of matrix anions. Sub-μM to μM concentrations of ClO4− and Br− are extracted from tap and sea water.
