Abstract
The solubility and sorption of radium and tin have been studied for a cementitious near-field environment.
The solubility of radium was observed to be greater than 10−7M, even with the addition of IM sulphate to the cement equilibrated water. The values of Rn for radium varied from 102 to 103 ml g−1 for the cement types and initial radium concentrations studied.
The solubility of tin was observed to be about 10−4M for a range of cement equilibrated waters above tin oxides and metallic tin. The solubility of tin was observed to increase with pH. Tin solubilities were not affected by the redox conditions. Tin was present in a range of particle sizes in the sorption studies. A value of RD of 104 ml g−1 was observed for tin species less than 0.45μm.
