Study the Transport Properties of Anion and Cation Exchange Membranes Toward Various Ions Using Chronopotentiometry

Original language description

The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about influence of the counter ion on the transport phenomena of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged groups, physical properties of the polymer and the preparation procedure. Chloride and nitrate were investigated as counter-ion in their sodium salts for anion exchange membranes while sodium, calcium, potassium and magnesium were selected as counter-ion in their chloride salts to study cation exchange membranes transport properties. First the current – voltage curve of an ion exchange membrane in a given solution was recorded to obtain the limiting current, then a constant current above the limiting current was used for chronopotentiometry measurement. In all the studied membranes the potential across the membrane remained constant for a time interval called the transition time τ, when a constant current was applied. Then the potential increased gradually to reach the steady state potential. The permselectivty and the transport number of a membrane was calculated using the corresponding transition time.
