MIGRATION BEHAVIOUR OF BROMINE ION IN LIQUID MEMBRANE
溴离子在液膜中的迁移作用

In this paper the migration rules of bromine ion is studied by using the choloroform bulk liquid membrane containing TnOA as carrier. The migration behaviour of bromine ion is influenced by the concentrations of bromine ion, carrier and the receive phase etc. The active migration of bromine ion is realizaed by virtue of acid basic reaction in receive phase. According to the soft hard acid-basic (SHAB) theory, the employment of a suitable carriercan improve the selectivity of bromine ion.
