| Abstract | BIOSIS COPYRIGHT: BIOL ABS. Based on a scientific study of the deposition of radioactive 51CrO42- species on ignited microcrystalline sulfates of lead, barium, and strontium along with their subsequent elution, a new experimental procedure for the concentration of aqueous extracts for microgram quantities of chromate species is developed. The feasibility of the procedure has been studied radiometrically on the basis of a systematic examination of the working conditions, e.g., carrying efficiency as a function of pH of the aqueous medium lattice/nonlattice ionic concentration, amount of carrier, carrying capacity of the carrier, and extraction of activity adsorbed under suitable experimental conditions. In principle, the procedure consists of two stages: first, the radioactive tracer species in a dilute aqueous solution is carried out under specified experimental conditions on a small quantity of ignited selected carriers; second, the carried activity can be largely leached out in a minimal amount |
