| Molybdenum hydrogen bronze and molybdenum trioxide have been discovered to be highly selective reagents for adsorption of actinides from aqueous solution. These reagents also can have capacities for the metals in excess of 100% by weight. The reason for the high capacities is that the mechanism of metal uptake is formation of insoluble molybdate salts and not ion exchange or redox processes. The results of the reactions of molybdenum blue and molybdenum trioxide with aqueous solutions of thorium nitrate, uranyl nitrate and uranyl acetate will be discussed. Also, the possibility for using these reagents in an industrial cycle for water purification will be presented. Essentially, such a cycle could be used for removal of actinides or other metals from water with water and ammonium hydroxide as the only reagents being consumed. |
