Claim 1
Independent Claim
66 words
A PROCESS FOR IMPROVING THE CARRYING OF PLUTONIUM ON AN INSOLUBLE CARRIER PRECIPITATE FROM A HYDRAZINECONTAINING NITRIC ACID SOLUTION OF PLUTONIUM IN A MAXIMUM VALENCE STATE OF +4 DERIVED BY DISSOLVING NEUTRONBOMBARDED URANIUM METAL IN NITRIC ACID WHICH COMPRISES ADDING TO SAID SOLUTION SUFFICIENT POTASSIUM NITRITE TO MAKE THE SOLUTION ABOUT 0.1 MOLAR AND TO DESTROY THE HYDRAZINE PRIOR TO CONTACTING THE SOLUTION WITH SAID CARRIER.
