Abstract
The authors explored the statics of Ca2+ and Sr2+ sorption from a saline, imitating the salt (mineral) composition of the blood plasma, and from blood plasma. As the plasma concentration was raised, there was a consistent decrease in ion sorption of KU = 2 X 8 cationite characteristic for M2+ complex formation in solution. Conventional constants for formation of complex compounds and mole proportions (%) of free (M2+) and complex forms (MLx-) metals were calculated. The time course of calcium and strontium sorption on KU = 2 X 8 ion-exchange resin from saline and blood plasma was studied. It was discovered that sorption from saline proceeded according to the externally diffusion kinetics type, whereas sorption from plasma according to the mixed type of the ion-exchange kinetics. The kinetic ratios were calculated for the indicated versions of sorption experiments. The mechanisms of sorption found in model experiments were extrapolated to dog experiments with blood decalcination, which supported the adequacy of experimental hemosorption under consideration.
