Incorporation of electrodialysers into the conduits of FIA systems: enhancement of the mass transfer of chloride anions through passive neutral membranes.
The viability of electrodialysis (ED) for the enhancement of mass transfer through passive neutral membranes in a flow injection system was investigated. A Spectrapore and Technicon type C membrane were evaluated using chloride anions as analyte. Both membranes showed an increase in mass transfer and the proposed electrodialyser/FIA system was applied for the determination of chloride in industrial effluents with results that compared very well with a standard titration procedure.
