A novel separation technique for bromide in the presence of various anions with a liquid
membrane was reported. Initially, bromide ion was oxidized by sodium dichromate in acidic
media (aqueous or source phase), followed by a continuous chloroform extraction (organic
phase). Next, a back-extraction of bromine into a second aqueous phase (receiving phase)
containing nitrite ions was conducted in order to reduce bromine into bromide. Parameters
affecting the transport efficiency as well as the influences of potential interfering ions in ...
