    摘要： A method and apparatus for extracting strontium and technetium values from biological, industrial and environmental sample solutions using a chromatographic column is described. An extractant medium for the column is prepared by generating a solution of a diluent containing a Crown ether and dispersing the solution on a resin substrate material. The sample solution is highly acidic and is introduced directed to the chromatographic column and strontium or technetium is eluted using deionized water.

    摘要： The present invention provides an apparatus and rapid methods for extracting strontium ions from urine to provide a concentrated and purified strontium-90 extract suitable for scintillation measurements. The methods remove organic compounds, pigments, and alkali metal ions that can interfere with quantitative determination of strontium-90 in urine. A method of the invention comprises acidifying urine and removing organic pigments therefrom, loading a known quantity of so-treated urine onto a diphosphonic acid-based ion-exchange resin; flowing aqueous methanesulfonic acid through the diphosphonic acid-based ion-exchange resin to elute alkali metal ions therefrom; eluting strontium ions off of the diphosphonic acid-based resin and on to a strontium extraction chromatographic resin with a concentrated aqueous nitric acid solution; subsequently flowing water or a dilute acid stripping solution through the strontium extraction resin to strip the strontium from the strontium extraction resin; and collecting the strontium-containing stripping solution eluting from the strontium extraction resin.

    摘要： The invention is a process for selectively extracting strontium values from aqueous nitric acid waste solutions containing these and other fission product values. The extractant solution is a macrocyclic polyether in an aliphatic hydrocarbon diluent containing a phase modifier. The process will selectively extract strontium values from nitric acid solutions which are up to 6 molar in nitric acid.

    摘要： An extraction chromatographic method for the preparation of .sup.90 Y of high chemical and radiochemical purity is disclosed. After an initial purification of a .sup.90 Sr stock solution and a suitable period of .sup.90 Y ingrowth, the solution is passed through a series of strontium-selective chromatographic columns, each of which lowers the .sup.90 Sr content of the mixture by a factor of about 10.sup.3. The .sup.90 Y remaining is freed from any residual .sup.90 Sr, from its .sup.90 Zr daughter, and from any remaining impurities by passing the sample through a final column designed to selectively retain yttrium.
