Abstract

The results are presented of specific electrical conductivity of commercially available anion
exchange membranes in the solutions of sodium chloride (NaCl) and of ampholytes: hydrotartrate
potassium (KHT), sodium dihydrophosphate (NaH2PO4), sodium hydrocarbonate (NaHCO3). It is shown
that specific electrical conductivity of the membranes in the solutions of ampholytes is much less in
comparison with sodium chloride solution. Several mechanisms of ampholyte anions transport in
membranes are discussed. Commercially available anion-exchange membranes are determined with good
conductivity in KHT, NaH2PO4 and NaHCO3 solutions.
