monovalent cations

Competitive Binding of K+ in the Presence of Na+ with Bovine Serum Albumin and Hemoglobin

Selective accumulation of monovalent cations K+, Na+, Rb+, Cs+ with albumin and hemoglobin is shown. Preferential sorption of potassium in the presence of sodium with test proteins is determined. It is shown that with increasing concentrations of sodium in the composition of aqueous solutions of the proteins, the amount of potassium bound by proteins increases.
