The electrodialysis mehtod was used to treat waste phosphoric acid containing Al and Mo ions in this study. The feasibility study of elctrodialysis for treatment of the waste phosphoric acid containing metal ions was investigated. The voltage, solution concentration and feed temperature mainly affect electrodialysis of the phosphoric acid containing Al and Mo ions. Higher voltage and feed temperature are beneficial for desalination of Al and Mo ions. At least, 30% of Al ions and 7% of Mo ions can be removed from the phosphoric acid by using the CMX/AMX, CM1/AM1 and CMX-SB/ACS ion-exchange membranes. An electrodialysis process seems to be a promising process to treat waste phosphoric acid containing Al and Mo ions.

The equilibrium sorption of uni-univalent electrolytes (NaCl, KCl) in heterogeneous cation exchange membranes with various contents of the ion exchange component and in ion exchange membranes Ralex was investigated. Using experimental data which express the concentration dependence of equilibrium sorption, validity of the Donnan relation for the systems under investigation was tested and values of the Glueckauf inhomogeneity factor for Ralex membranes were determined. Determination of the equilibrium sorption allows the effect of the total content of internal water and of the ion-exchange capacity on the distribution coefficients of the electrolyte to be determined.
