PREPARATION OF ELECTRODEPOSITED SOURCE FOR ZN-65

Electrolytes of alkaline zincate, acidified zinc sulphate, zinc-ammoni a, zinc-ammonia-EDTA, zinc-EDTA/NaOH have been examined in order to ve rify their applicability for electrodeposition (ED) of zinc on stainle ss steel (SS) disc at ppm level. Operating parameters suitable for ED of zinc at 90% deposition (amount of zinc removed from plating solutio n) on SS disc using a total 1 ppm zinc in a 5 cm(3) both volume were d etermined. It helped to prepare radioactive source (Zn-65) using inact ive Zn as carrier. Speciation of zinc in a Zn-oxalate-EDTA-ammonia bat h has been computed.
