Cso Rb. and K in the exchange extraction series. Anequeous solution of the hydroxide of the metal being investigated was shaker,, for 1.5 hours at 2500 with an equal.volume of fatty.scid in agraduated cylinder furnished witb 9, stopper. The starting concentration of' cesium, rubidiuni, and potassium in the solutions varied from 0,5 to 0,015 N. and the starting concentration of lithium from*0.8 to-O.-l N. The extractability was evaluated from the activity coefficient in the aqueous phase. After separation of the phases, their alkali metal content was determined, The article continues with a-descriptionof the method of spectral anlysis. Experimental results are sho= in two Igrge tables. The sensitivity of the determination was from 1 x 10-P to 1 x 10-7%. The coefficient of variation varied from 15 to 40% for diff9ront elements* The metbod is. said to ~be in actue.1 plant use. Orig. art. buz: 1 figure and 2 tables.
