Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
69 words
THE METHOD OF SEPARATING PLUTONIUM IN A VALENCE STATE NOT GREATER THAN +4 FROM URANIUM IN THE URANYL STATE WHICH COMPRISES PRECIPITATING PLUTONIUM BY MEANS OF A PEROXIDE FROM A SOLUTION HAVING A PH NOT GREATER THAN 7 AND CONTAINING SAID ELEMENTS IN THE PRESENCE OF AN ANION SELECTED FROM THE GROUP CONSISTING OF SULFATE, ACETATE, AND TERTRATE WHICH FORMS A COMPLEX ION WITH URANIUM WHICH PREVENTS ITS PRECIPITATION.
Claim 2
Independent Claim
69 words
THE METHOD OF SEPARATING PLUTONIUM IN A VALENCE STATE NOT GREATER THAN +4 FROM URANIUM IN THE URANYL STATE WHICH COMPRISES PRECIPITATING PLUTONIUM BY MEANS OF A PEROXIDE FROM A SOLUTION HAVING A PH NOT GREATER THAN 7 AND CONTAINING SAID ELEMENTS IN THE PRESENCE OF AN ANION SELECTED FROM THE GROUP CONSISTING OF SULFATE, ACETATE, AND TERTRATE WHICH FORMS A COMPLEX ION WITH URANIUM WHICH PREVENTS ITS PRECIPITATION.
Claim 3
Dependent Claim
76 words
IN THE METHOD OF SEPARATING PLUTONIUM FROM FISSION PRODUCTS AND URANIUM IN THE URANYL STATE IN A SOLUTION CONTAINING SAID PRODUCTS AND PLUTONIUM IN A VALENCE STATE NOT GREATER THAN +4, THE STEP WHICH COMPRISES ADDING TO THE SOLUTION A SOLUBLE THORIUM COMPOUND, AMMONIUM ION, AND AN ANION SELECTED FROM THE GROUP CONSISTING OF SULFATE, ACETATE, AND TARTRATE WHICH FORMS A COMPLEX ION WITH URANIUM BUT WHICH DOES NOT PRECIPITATE RARE EARTH COMPOUNDS FROM ACID SOLUTION.
