Thin cation-exchange foils
Treatment of commercial polystyrene sheets with fuming sulfuric acid produces a thin layer of cation exchanger. The ion exchange capacity of the layer is measured by an isotope dilution procedure which utilizes Th^2^2^8 and Th^2^3^2. At the same time the thickness is found from the yield of Ra^2^2^4...

Thin cation-exchange foils |
| abstract |
Treatment of commercial polystyrene sheets with fuming sulfuric acid produces a thin layer of cation exchanger. The ion exchange capacity of the layer is measured by an isotope dilution procedure which utilizes Th^2^2^8 and Th^2^3^2. At the same time the thickness is found from the yield of Ra^2^2^4 which escapes from the foils as α-decay recoils.A specific capacity of 5.6 milliequivalents per gram can readily be obtained, and the thickness can be varied from a few to several hundred micrograms/cm^2. The foils have been used for simple and fast preparation of α sources. |
