Abstract
The optimum concentration of the extractants for rapid radiostrontium concentration is 0.1M HB (chlorinated cobalt dicarbollide acid) and 1. 5% vol. of Slovafol 909 in a mixture of CCl4(40%) and nitrobenzene. Th e recommended initial carrier concentration is 2 . 10(-4) M Sr initial aq. pH approximately 4.3, time of shaking 3 min. Yield in the range 8 0-97% can be achieved in rapidly concentrating Sr from 1 dm3 aqueous p hase into 10-20 ml of the extract. The yield decreases with increasing Ca concentration in the model water. The time needed for the concentr ating does not exceed 30 min.
