摘要：

During this work, controlled redox potential methodology was adopted for the complete separation of traces of uranium from the host matrix of mixed hydroxide of Iron. Precipitates of Fe(+2) and Fe(+3) along with other transuranic elements were obtained from acid leached solution of soil by raising the PH to 9 with 14N ammonia solution. The concentration of the uranium observed in the soil samples was 200-600ppb, whereas in sediment samples, the concentration range was 61-400ppb. (C) 2008 Elsevier Ltd. All rights reserved.
