- Abstract
- An experimental study of the equilibrium distribution of cations in the system of Dowex 50 sulfonic cation exchanger and an aqueous solution of picolinic acid and iron chloride was carried out. A high concentration of iron and picolinic acid complexes was obtained in the Dowex 50 sulfonic cationite phase. The possibility of calculating the equilibrium counterionic composition of Dowex 50 sulfonic cationite from the equilibrium constants of binary ion exchanges and the known composition of the solution is shown. Sulfocationite Dowex 50 is proposed as a container for biologically active preparations based on picolinic acid and Fe3+ cations.
