Abstract
To improve the accuracy of projected releases from radioactive waste disposal systems, the sorption characteristics of steel corrosion products were investigated with a special emphasis on competitive sorption between Sr and Na. The corrosion rate of steel exposed to various environments was studied qualitatively and, with some systems, quantitatively. Traditional and non-traditional adsorption/desorption experiments on steel corrosion products using 0.01-M NaCl and 0.001-M NaCl solutions with two different concentrations of Sr were performed including one system with slow flow. Langmuir and Freundlich adsorption isotherms were used to analyze the data and to characterize the ion exchange capacity of the sorbate.
