Rb-2 Rubidium SEPARATION TIME: 3 min SEPARATION TECHNIQUE: Precipitation PRODUCTION MODE: Batch REPERENCE: Arlt, R, Beyer, G. J., Herrmann, E., Habenicht, W., and Tyroff, H., “On the identification of 78Rb/T = 19 min,” Radiochem. Radioanal. Lett. 10, 173–175 ( 1972). PROCEDURE: The following procedure was used after initial mass separation. A Zr-Nb alloy target irradiated with the external beam of a synchrocyclotron was used in the ion source of a mass separator. The surface ionization source produced only rubidium and strontium ions. After mass separation, the ions were collected on an aluminum-coated polyester tape. The deposited rubidium and strontium were dissolved in a few drops of aqua regia. The solution was mixed with 60 mg each rubidium and strontium carriers; strontium was precipitated with H2SO4 and filtered. From the filtrate, rubidium was precipitated as perchlorate by the addition of perchloric acid. Rb-3 Rubidium SEPARATION TIME: ~1 min SEPARATION TECHNIQUE: Precipitation PRODUCTION MODE: Batch REFERENCE: Litz, L. M., Ring, S. A., and Balkwell, W. R., “The 1.25-min 82Rbm daughter of 27-day 82Sr,” Phys. Rev. 92, 288–290 ( 1953). PROCEDURE: This procedure was used for separation of rubidium from purified strontium parent. After the establishment of the parent-daughter equilibrium in the initially purified strontium solution, perchloric acid, rubidium, and strontium carriers were added, and the mixture was boiled to fuming. The solution was cooled in ice, and rubidium was precipitated as perchlorate by the addition of cooled absolute alcohol. The precipitate was filtered, washed with alcohol, and Used for counting.
