Description/Abstract:
A METHOD IS DESCRIBED FOR ELECTRODEPOSITING VARIOUS ALPHA-EMITTING NUC LIDES, SINGLY OR IN COMBINATION, ONTO A STAINLESS STEEL CATHODE. THE N UCLIDES ARE DEPOSITED AS HYDROXIDES TO BETTER THAN 98 PERCENT IN 50 MI NUTES FROM AN AMMONIUM CHORIDE-AMMONIUM OXALATE ELECTROLYTE. THE OPTIM UM CONDITIONS WERE DETERMINED BY STUDYING THE EFFECTS OF TIME, CURRENT , ELECTROLYTE CONCENTRATION, ELECTRODE SPACING, PH, AND THE EFFECT OF HYDROXYLAMINE AS A REDUCING AGENT. ADDITIONAL STUDIES INCLUDE ELECTROL YTE VARIATION WITH STRONG ORGANIC ACIDS AND A DIVERSE ION STUDY OF VAR IOUS ANIONS AND CATIONS. THE USE OF A CHELATING AGENT REDUCED THE INTE RFERENCE OF SOME CATIONS AND GREATLY IMPROVED THE YIELD AND PRECISION OF SEVERAL NUCLIDES. FLUORIDE MARKEDLY ALLEVIATED THE INTERFERENCE CAU SED BY IRON, ALUMINUM, NATURAL THORIUM AND ZIRCONIUM.
