PERMSELECTIVITY OF VARIOUS CATIONS ACROSS CATION-EXCHANGE MEMBRANE
Original language description
The main goal of this work was to evaluate the permselectivity between different cations through RALEX® CM PES cation-exchange membrane. Removal rate and permselectivity of cations K+, Na+, Ca2+, Mg2+ was measured and compared for applied voltage of 5 V and 15 V. For measurement, 10 l solution was prepared containing sodium nitride, potassium nitrate, calcium nitrate and magnesium nitrate. 5 l of solution was used initially as a diluate solution and 5 l as a concentrate solution in electrodialysis. Experiment showed differences between 5 V and 15 V. The rate of removal Ca2+ and Mg2+ ions were faster than for K+ and Na+ ions for constant voltage 5 V during electrodialysis. On contrary, rate of Ca2+, Mg2+ and K+ was almost the same for applied voltage of 15 V and Na+ removal rate was close to rate of other ions. This showed that RALEX® CM PES membrane preferably permeates divalent ions at low applied voltage.
