The Cr (VI) transport numbers were calculated. If the current does not reach a limiting value, the ccchromium transport numbers increases with increasing in amount of hydrated zirconium dioxide in matrix. Acidification of the solution as well as inceasing in chromium amount allows us to enlarge the membrane selectivity. It should expect, that use of membranes with a larger degree of completition of pores with ion-exchange component will allow us to reach a higher efficiency of electrodialysis process.
