BIOSIS COPYRIGHT: BIOL ABS. Laboratory experiments were performed to simulate the interaction of contaminated pore fluids with a variety of industrial materials. The objective was to evaluate the materials for use in a chemical barrier under a repository containing uranium mill tailings. Pore water would pass through the barrier, but contaminants would remain fixed in the solid fraction. More than 99% of the dissolved uranium in a synthetic pore fluid (initial uranium concentration fo 30.0 mg) was extracted by the addition of hydrated lime, fly ash, barium chloride, calcium phosphate, titanium oxide, peat, and lignite. More than 96% of the molybdenum (initial molybdenum concentration of 8.9 mg/L) was extracted by ferrous sulfate, ferric oxyhydroxide, titanium oxide, peat, hematite, calcium chloride, and barium chloride. Some materials were effective only for a limited range of pH values. Extraction was caused by both precipitation (as calcium uranate, calcium molybdate, ferrous molybdate, or bariu
