Determination of the solubility of difficultly soluble compounds using nonisotopic radioactive indicators
We established the rules governing the transfer into solution of a microelement, truly isomorphous with the compound of a macroelement, with partial solution of the solid phase containing the microelement. A method was developed for determining the solubility of difficultly soluble compounds using nonisotopic radioactive indicators, truly isomorphous with the given compound. The effect of the degree to which thermodynamic equilibrium was attained between the whole precipitate and the saturated solution on the character of the curves used for determining solubility was elucidated. We propose a method for determining the solubility of difficultly soluble compounds in solutions containing similar ions. The relations found were confirmed by determining the solubility of BaSO4 with Sr90 and of K2PtCl6 with Cs134.
