Abstract
Sorption characteristics of modified poly(ethyleneimine) supports whic h contain ammonium, carboxymethyl or phosphonomethyl groups have been determined for uptake of molybdenum(VI), rhenium(VII) and vanadium(V). Results suggest the separation of rhenium(VII) toward molybdenum(VI) from loaded N-carboxymethyl derivative by selective elution with 1M su lfuric or perchloric acid. Moreover, vanadium(V) should be also select ively eluted from molybdenum(VI), iron(II) or iron(III).
