The extraction of selected divalent (Ca+2, Sr+2, Ba+2, Ra+2, Pb+2, UO2 +2) and monovalent (Na+, K+, Rb+, CS+, TI+) metal cations at tracer concentration level by a recently introduced strontium-selective extraction chromatographic resin has been studied as function of the nitric acid concentration in the range − 0.1-7 M. The data have been explained by combining the metal extraction, the acid extraction, and the aqueous phase metal complication equilibria. Conditional metal extraction equilibrium constants have been estimated by using calculated activity coefficients of the metal nitrate salts in the nitric acid solutions. The extraction constants have been used to predict the effect of macroconcentrations of sample matrix constituents on the extraction of Sr+2 or Pb+2 by the strontium-selective resin.
