| Abstract: | A new methed has been developed for the simultaneous determination of microgram quantities of uranium and thorium with Arsenazo III in hydrochloric acid medium. Uranium,in the range 1.0 - 12.0ug/ml,Thorium in the range 0. 1 - 1.5ug/ml have been determined simultaneously with good precision. The procedure does not require separation of uranium and thorium,and allows the de-termition of both metals in the presence of alkaline - earth metals and zirconium,but lanthanides interfere. |
