A review of the literature was made on the adsorption of ions by the compounds of iron and related compounds. The investigation of the absorption of calcium on hydrous ferric oxide and limonite covered a range of solution pH from 6.0 to 10.0 and equilibrium calcium solution concentrations from 1.0 x 10/sup -4/ to 5.0 x 10/sup -2/ N. Calcium solution concentrations were determined by the EDTA titration method. The investigation of the adsorption of strontium on hydrous ferric oxide and limonite covered a range of solution pH from 6.0 to 12.0 and equilibrium strontium solution concentrations from 1.0 x 10/sup -7/ to 1.0 x 10/sup -4/ N. Strontium solution concentrations were determined by the radioactive tracer technique using Sr-89 tracer. There was no significant adsorption of either calcium or strontium on hydrous ferric oxide at pH 8.0. The fraction adsorbed increased with increase in pH (7.0 and above) and increased with decrease in equilibrium solution concentration. The distribution coefficients for calcium and strontium between the solid and liquid phases increased with increase in pH and increased with decrease in equilibrium solution concentration. The adsorption of calcium and strontium on limonite was on the order of one-tenth of the adsorption of hydrous ferric oxide. A study was made of the percolation rates of liquid through a few selected samples of soil taken from areas near the low level radioactive waste disposal basins of the Savannah River Plant. The study has indicated that seepage rates through soils described as sandy clay and clayey sand are fairly high for liquids with pH values below 6. When feed solutions were increased above pH 6 seepage rates decreased; at pH values of 10 and above seepage rates would even stop. Increased flow rates could not be restored with acid feed solutions. Acid feed solutions showed increased flow rates over initial rates and approached a constant flow. Sodium nitrate solutions of 1M have little effect on flow rates through clayey sand soils. (auth)
