Abstract

Cilj ovog rada je ispitivanje mogućnosti kromatrografske izolacije stroncija i olova iz kompleksnih smjesa pomoću izmjenjivaču SerdolitTM CG-400 I koji je uveden kao zamjena za Amberlite CG-400. Ispitivan je utjecaj sastava otopine na vezanje kationa, polarnosti alkohola, koncentracije dušične i klorovodične kiseline te udio vode u otopinama. Određena je krivulja prodora i eluiranja stroncija i olova na kolonama punjenim izmjenjivačima Amberlite CG-400 i SerdolitTM CG-400 I te je krivulja prodora uspoređena s teorijskom krivuljom. Kreiran je postupak izolacije olova i stroncija od kalcija i ostalih elemenata u modelnog uzorku. Koncentracije svih kationa određenu su atomskom apsorpcijskom spektrometrijom a aktivnost izotopa gama spektrometrijom.

Abstract (english)

The intention of this work is to examine the possibilities of chromatographic isolation of strontium and lead from a complex mixture by using exchanger SerdolitTM CG-400 I which was introduced as a replacement for the Amberlite CG-400. Influence of solution composition on the binding of cations, the polarity of the alcohol, the concentration of nitric and hydrocloric acid and water content of the solutions are also determined. Curve of penetration and elution curve of lead and strontium are done on column of Amberlite CG-400 and SerdolitTM CG-400 I and the curve of penetration is compared with the theoretical curve. A procedure of isolation lead and strontium from calcium and other elements on model sample is created. The concentrations of cations were measured by means of specific atomic absorption spectrometry and activity of isotopes by gamma spectrometry.
