Research output: Contribution to journalArticle


The calculation data of equilibrium concentrations for calcium ions in ammonium medium have been reported in the paper. The "P2S2R3KA" program was used. It was shown the equilibrium concentrations for calcium ions decrease from 84.16 to 1.0 mg/dm3 in the model solution. The reactant diffusion rate was determined.
