Electrodialysis of 106Ru, 56\u2757\u27 58Co and 65Zn in Sea Water Through Ion-Exchange Membranes

The procedure for · studying the migration of microconstituents dur ing electrodialysis of sea water t hrough ion-exchange m em bran es i s described. On the b asis of experimen ts with 106Ru the possibility of separating various stable physico-chemical forms of ruthenium from sea water is presented. The separation process was controlled by measuring the radio activity of sea water during electrodialysis, and the adsorption on ion-exchange membranes in order to establish whether variou s stable physico-chemical forms of 106Ru exist in sea water and whether they can be successfully separated b y t h i s m ethod. For comparison of the results, all experiments were also performed using both 56,57, 58Co and 65Zn in sea water
