| Abstract: | Commercial phosphoric acid produced by the wet method is not a purecompound. It contains many contaminants. This paper studied the effect ofcertain cations in the commercial phosphoric acid produced by SIAPE wet methodin Homs General Fertilizer Company on the distribution coefficient (K d )ofuranium . The effect of Fe 3+ , Fe2+ , Mg2+, Ca 2+ , Al 3+ and V 5+ on uranium extractionby D2EHPA/TOPO was investigated according to the factorial design method.The results obtained showed that Al 3+ and Ca 2+ hada marked beneficial effect on uranium extraction while Mg 2+ ,Fe 3+ and V 5+ had a negligible effect. An increasein Fe 2+ led to a decrease in the extraction of UO 32+ from phosphoric acid. |
