[Cation-exchange method of determining the state of magnesium, calcium and strontium in blood plasma]

A method of cation metabolism on cationite KY=2X8 in the balanced-salt form was applied to the study of sorption of Mg2+, Ca2+ and Sr2+ ions from physiological solutions and solutions containing blood plasma of dogs and physiological saline in different ratio. Balance constants, which permitted to determine mol fractions (or the content percentage), of "free" and "bound" ions of the corresponding metals were calculated from the experiments.
