摘要：
A rapid extraction of trace amounts of strontium from calcium with a nitrobenzene solution of sodium dicarbollylcobaltate (NaDCC) in the presence of 15-crown-5 and the tetrasodium salt of ethylenediamine-N,N,N',N'-tetra-acetic acid (Na4L) in the aqueous phase was developed. The separation factor alpha(Sr/Ca) was approximately 10(5).
