CESIUM MIGRATION IN SATURATED SILICA SAND AND HANFORD SEDIMENTS AS IMPACTED BY IONIC STRENGTH

Materials and methods for artificial pore water and Caesium analysis in experiments on tanks filed with silica sands and sediments. Batch sorption experiments and column transport experiments are carried. Column parameters and operating conditions are given. Theory of the migration through packed column with 1D advection-dispersion equation. Caesium sorption isotherms are obtained with different NaCl solutions and distribution coefficients given. Caesium breakthrough curves for different ionic strength NaCl solutions. Discussion of the different results obtains with silica sand and sediment.
