SEPARATION AND CONCENTRATION OF ELEMENTS BY REVERSED PHASE PARTITION CHROMATOGRAPHY

The method of column extraction chromatography with inert supporting materials facilitates selective or group concentration of traces of elements with an enrichment coefficient more than io and the separation of complex compounds of elements which have similar properties. Contamination of the solution under investigation is negligible because of slight absorption and the use of small extractant amounts. The method proved to be very convenient for the separation of short-lived isotopes. An additional advantage is the possibility of automatic control of the method. The method of reversed phase partition chromatography is now fairly widely used in radiochemistry, analytical chemistry and nuclear technology for the separation of elements having similar properties. Reversed phase partition chromatography has an undoubted advantage in comparison with ordinary solvent extraction because it allows concentration of traces of elements with high enrichment coefficients. Hence, the method is of particula
