Sorption of Picolinic Acid and Zinc Cations by Dowex 50 Sulfocationite
The equilibrium distribution of components between the Dowex 50 sulfocationite and an aqueous solution containing picolinic acid and zinc nitrate was studied. The total concentration of the zinc cation and its complex with picolinic acid in the polymer reached 1.1 M. The possibility of preliminarily calculating the counterionic composition of sulfocationite based on the equilibrium constants of binary ion exchanges and the known composition of solution is shown.
