摘要：

Commercial phosphoric acid produced by the wet method is not a pure compound. It contains many contaminants. This paper studied the effect of certain cations in the commercial phosphoric acid produced by SIAPE wet method in Homs General Fertilizer Company on the distribution coefficient (Kd) of uranium The effect of Fe3+, Fe2+, Mg2+, Ca2+, Al3+ and V5+ on uranium extraction by D2EHPA/TOPO was investigated according to the factorial design method. The results obtained showed that Al3+ and Ca2+ had a marked beneficial effect on uranium extraction while Mg2+, Fe3+ and V5+ had a negligible effect. An increase in Fe2+ led to a decrease in the extraction of UO22+ from phosphoric acid.
