Abstract

AbstractA literature review and screening study suggest the feasibility of using low‐cost organic materials within a permeable reactive barrier (PRB) to treat ura‐nium‐contaminated water. Natural peat deposits remove and sequester ura‐nium from ground water under certain geochemical conditions while several species of bacteria, including Desulfovibrio desulfuricans precipitate soluble uranium from solution. Cation exchange capacities were measured for saw‐dust and peat, materials to be used in construction of a small‐scale PRB. Re‐sults of a literature review and the cation exchange capacity measurements suggest that organic materials, such as peat, can be used to remove soluble uranium from contaminated water. © 2006 Wiley Periodicals, Inc.
