PREPARATION OF THIN ELECTRODEPOSITS OF ACTINIDES FROM AQUEOUS SOLUTIONS OF (ETHYLENEDIAMINE)TETRAACETIC ACID (in French)
The cathodic electrodeposition of several actinide elements from aqueous solutions of EDTA partially neutralized with ammonia is studied. On platinum cathodes, the deposited films are thin, adherent, and reasonably uniform. A yield of 90 to 95% can be achieved under suitable conditions. The rate of deposition is the same for tripositive transplutonium elements, but plutonium deposits preferentially at the beginning of the electrolysis; on the other hand, the uranyl ion has a deposition rate lower than the transplutonium elements. The presently described technique is not limited to tracer scale since submicrogram and microgram amounts of various elements can produce satisfactory deposits. For plutonium, deposits up to 300 of 70%. (auth) be concluded that the acids investigated formed chelate complexes with U(VI). (tr-auth)
