Description
Three procedures for separating of Cs and Rb from geological samples were investigated. The fractional recovery was determined by radioactive tracers and by RNAA. In the first procedure 0.2g of irradiated sample is fused with Na2O2, acidified and passed through a clinoptilolite zeolite column. Cs and Rb were eluted with 7.5M HNO3; chemical yields are in the range 93-98%. The second procedure is a supplement to the SUNDBERG and BOYNTON (1976) procedure; a previously discarded anion-exchanger effluent, containig Cs, Rb, Co, Na, etc., is passed through a clinoptilolite column. Cs and Rb are eluted with 7.5M HNO3; yields are in the range of 82-94%. A third separation involves precipitation of Cs and Rb from the effluent and washings with sodium tetraphenylborate (NaBPh4); yields are 64-83%. (author) 8 refs.; 4 tabs
