A RAPID SEPARATION OF FISSION PRODUCTS BY PAPER ELECTROPHORESIS (in Japanese)
A rapid separation of Cs/sup 137/, Sr/sup 90/, Ce/sup 144/, and Zr/sup 95/ by paper electrophoresis was studied. The filter strips were placed in a background electrolyte. After removal from the solution, they were blotted between sheets of dry paper. The strips were sandwiched by plastics plate and cooling bath, and screwed tightly. They were allowed to equilibrate for 30 minutes. The sample solution (0.005 ml) containing Cs/sup 137/, Sr /sup 90/ , Ce/ sup 144/, and Zr/sup 95/ was spotted at a point 10 cm apart from one end of the filter strip through a hole of plastics plate, and then the hole was covered with cellophane tape. The most suitable conditions for the separation were investigated in detail, using tantaric acid, citric acid, acetic acid and formic acid. Separation of trace Cs/sup 137/, Sr/sup 90/, Ce/sup 144/ and Zr/sup 95/ from each other was carried out in only 25 minutes using 0.05M ammonium citrate, pH 3.5, as the electrolyte at 1080 v, and the mixture of those with 0.05M carrier of each was separated in only 20 minutes at 1440 v.
